## Introduction

Many maths students disagree that an object's length and height are separate dimensions; instead, they believe that these two dimensions are equivalent. However, this is not true; there are slight variations in length and height in addition to their shared traits.

## Length vs. Height

The length refers to the extent of an object, i.e., it identifies how long an entity is. On the other hand, height indicates the object's altitude, which indicates how tall an object is.

## What Is the Length?

The measurement or extent of something from end to end is referred to as length. In other terms, it is the largest of an object's two dimensions or its highest three dimensions. The length and breadth, for instance, are the dimensions of a rectangle. Additionally, the International System of Quantities defines length as a quantity with the dimension distance.

### Unit Of Length?

The International System of Units (SI) system's fundamental unit of length is the meter, abbreviated as m. When the length is given in the correct units, such as 2 meters or 200 cm for a table, 15 meters for a string, etc., this is possible. As a result, understanding the presented parameters in number format is aided by the units of measurement.

### Units To Measure Length

Several units, such as meters, centimeters, feet, inches, handspan, foot-span, etc., can be used to measure an object's length. The units used to measure length are divided into two categories: -

#### Nonstandard units

The non-standard units lack any type of defined numerical measurement. Both the measurements of the objects and the people are different.

As an illustration, a child and his father are using their hands to measure a painting. Therefore, the length they will receive will be different since a child's handspan is typically shorter than an adult’s. Handspan, foot span, finger breadth, thread, rope, etc. are a few examples of non-standard length units.

1. Handspan: - The maximum distance between the tips of the thumb and the little finger is known as the handspan. Depending on how big your hand is, it is typically around 8 inches.
2. Foot span: - The distance between the tip of the big toe and the heel of the foot is known as the foot span.

#### Standard Units

Standard units are specified and remain constant from one person or thing to another. Assume that two people are using rulers to measure the length of a pencil. They will obtain the same value if they utilize conventional units.  Centimeters, meters, kilometers, inches, feet, and yards are some examples of standard units used to measure length.

### The two categories of length measurement units are as follows:

Metric System: - There are seven different units in the metric system: kilometer, hectometer, meter, decimeter, centimeter, and millimeter. These units are related to one another. Meters serve as the basic unit. Following is a chart showing how each additional unit compares to the base unit (meters): -

• 1000 meters make up one kilometer (km).
• 100 meters equals 1 hectometer (hm).
• 10 meters is one decameter (dam).
• 1metre (dm) is equal to one-tenth of a meter (0.1 m).
• 1 centimeter (cm) is equal to one-hundredth of a meter (0.1 m).
• 1 millimeter (mm) is equal to one-thousandth of a meter (0.001 m).

Imperial System: - In the imperial system, there are units for feet, yards, inches, etc. The relationship is provided by: -

• 1 yard = 3 feet
• 1 feet = 12 inches

Metric To Imperial System

• 1 m = 3.28 feet
• 1 m = 39.37 inches

Imperial To Metric System

• 1 inch = 2.54 cm
• 1 foot = 30.48 cm
• 1 foot = 0.3048 m

### Tools For Measuring Length.

1. Rulers: - Rulers are rigid and have straight edges. The ruler is marked on one side in inches and on the other in centimeters. For lesser lengths, like the length of a pencil or notebook, rulers are useful.
2. Measuring Tape: - Flexible straight edges with graduated markings are called tape measures. You'll need to locate a tape measure that uses the unit system you require because most tape measures only measure one unit system (metric or U.S. customary). These instruments can bend, making them useful for measuring the overall length of an object that has more than one dimension (such as the diameter of a wooden block or the measurement of the waist).
3. Odometers: - Odometers are devices that track the distances that bicycles and other long-distance moving vehicles cover. Pedometers track the considerable distances that a person or other living thing walks. These instruments perform well for measuring miles and kilometers, but they require no human interaction and are calibrated by experts.
4. Meter sticks: - The length and design of yardsticks and meters are identical. Both have stiffness and straight edges. Yardsticks measure all distances up to 3 feet, whereas meter sticks measure all distances up to 1 meter.

### How Do You Measure Length?

A ruler is a two-sided object. We may see inches on one side and centimeters/millimeters on the other. To determine an object's length, use the procedures below:

Step 1: - Select the unit in which you want to express an object's length. Use the ruler's cm/mm side if you need a value in cm/mm. Use the ruler's inches side if you want the value in inches.

Step 2: - On one end of the ruler, locate the 0 mark. Align the zero mark with the edge of the measurement target.

Step 3: - Look at the object's endpoint and make a note of the value.

## What Is Height?

The height of anything or anybody can be used to measure it from the bottom up or from head to toe. In other words, one's height provides information on their height. We could measure how much taller we become with age. The average heights of men and women in various countries are regularly compared.

In mathematics, an object's height is defined as the vertical distance between its top and base.  Sometimes, it has the designation "altitude."

In coordinate geometry, height refers to an object's length along the y-axis.

### Ways of Measuring Height

We can use a variety of measuring tools to determine the height of an object or a person. Tools for measuring vertical length include: -

1. Rulers: - Rulers are rigid and have straight edges. The ruler includes marks on both sides, one in inches and the other in centimeters. For lesser lengths, like the length of a pencil or notebook, rulers are useful.
2. Measuring Tape: - Flexible straight edges with graduated markings are called tape measures. You'll need to locate a tape measure that uses the unit system you require because most tape measures only measure one unit system (metric or U.S. customary).
3. Yardsticks: - The structures of yardsticks and meter sticks are comparable. Both have stiffness and straight edges. Yardsticks measure all distances up to 3 feet, whereas meter sticks measure all distances up to 1 meter.
4. Stadiometer: - A height meter, often known as a stadiometer, is a device used to gauge an individual's height. The most well-known are those that can be moved and installed at any place and are mounted on a wall.
5. Clinometer: - An instrument called an inclinometer or clinometer is used to calculate the slope, elevation, or depression of an object with regard to the direction of gravity.
6. Altimeter: - An altimeter is a device that measures altitude, the distance of a point above sea level.

### Units Of Height

From little creatures like ladybirds in the garden to enormous whales in the sea, our world is made up of all sizes! It can be difficult to gauge their height using the same units. To make the work easier, we, therefore, employ a variety of size units. Included among the units of measurement are meters (m), feet (ft or '), inches ("), and so forth.

It is best to use the proper units of measure when expressing the vertical length of distinct items.

• Units of millimeters or centimeters can be used to measure small objects like an eraser or your nail.
• A person's height should be measured in feet and inches or centimeters.
• The height of a structure or monument is measured in units like meters or feet.

### How To Determine Whether Two Items Are Of the Same Height?

To gauge size and determine whether two objects are the same height, we can use various measurement tools like a scale or inch tape. Sometimes, because the things are measured in different units, we are unable to directly determine whether they are the same size. The procedures to determine whether two or more objects are the same height are as follows: -

Step 1: Convert the measurement units and make them all equal.

Step 2 is to compare the objects' heights using the same units.

### Units Conversion

• 1 kilometer (km) =1000 meters
• 1 meter (m) =100 cm =1000 mm
• 1 centimeter is equal to 10 millimeters, or 1 meter.
• 1 millimeter =0.001 meter
• 1 yard =3 feet =36 inches
• 1 foot =12 inches

### Origin Of the Word Height

Height comes from the word "high," which is derived from the Old English word "héah" and has Proto-Indo-European roots.

### Some Fun Facts About the Term “Height”

1. On a graph, height is measured along the vertical axis.
2. The distance from sea level to an altitude is measured.

## Main Difference Between Length and Height (In Points)

Regarding the disparity between length and height, the following points are significant:

1. The length of an object is essentially its measurement from end to end. Contrarily, height refers to the measurement of an object's height from its base to its top.
2. In contrast to height, which is a measure of how tall someone or something is, length determines how long something is.
3. Height is in alignment with the Y-axis, which represents the vertical side of something, whereas length is measured along the X-axis, which is essentially the horizontal side of something.
4. Length is the longest facet of an object. The side of an object that would be upward in its natural configuration is referred to as the object's height, on the other hand.
5. Length may be used for one-dimensional objects whereas height cannot be used for one-dimensional objects.

## Parallelism Between Length and Height

1. Same units are used to measure both length and height.
2. The length and height are calculated using the same units used to measure distance.
3. The units used to measure length and height are feet, inches, yards, and meters.

## Conclusion

In general, length and height are used to determine an object's length and height, respectively. As a result, we can draw the conclusion that both length and height are used as units of measurement and as was already indicated, that there are certain similarities and differences between them. As people moved from nomadic ways to settled areas, measurement data became crucial. In our daily life, we need to measure several things including time, accuracy, and distance. By quantifying theseproperties, we may be able to better understand the environment. The two are obviously two different geometric ideas. Because the measurement changes with location, the location of an object is important in determining the length and heightof the object. The length and height of an object are determined by its vertical and horizontal position.
