Length is the concept which is known for most of the students. The term “length” is used for identifying the size of an object or the distance from one place to another place. There are different methods to calculate the length of the given objects. Learn about the conversion of measuring length from here. All you have to do is to know the formulas.

## Length – Definition

Length is defined as the measure of distance. It is the international system of measuring quantities with dimension distance. The base unit for length is the meter. The metric units of length are divided into S.I and non-SI units.

### How to Measure Length using Different Units?

The length of an object or something can be measured by using different types of measurement units. They are as follows,

1. Miles

2. Yard

3. Foot

4. Inch

5. Thou or Mil

6. Centimeter

7. Meters

8. Kilometers

**Mile:**The symbol of a mile is ‘mi or m’. A mile is a unit of length in the US customary systems of measurement. It is a unit of distance.**Yard:**A yard is a unit of length that is equal to 36 inches or 3 feet.**Foot:**Foot is the unit of length in US units that is equal to 12 inches.**Inch:**An inch is a small unit of length. 12 inches make up a foot and 36 inches make up a yard.**Mil or thou:**The mil or thou is used in the United States to measure the length.**Centimeter:**The concept of centimeter is based on the meter. It is the unit of length in the metric system that is equal to one-hundredth of a meter. The symbol of the centimeter is ‘cm’.**Meter:**A meter is the basic unit of length in the metric system. The symbol of meter is ‘m’. 1 meter = 100 centimeters.**Kilometer:**A metric unit of distance is equal to 1000 meters. The relationship between kilometer and meter is 1 km = 1000 meters.

There is an interesting and easy way to remember the units of length.

### Length Examples

Check out the below problems to know how to calculate the length of an object.

**Example 1. **

Convert 8 meters into centimeters?

**Solution:**

We know that,

1 meter = 100 centimetres

8 meters = ?

Multiply 100 by 8 then we get 800

Therefore 8 meters = 800 centimetres

**Example 2. **

Convert 3 kilometers into meters?

**Solution:**

We know that,

1 kilometre = 1000 meters

3 kilometers = ?

Multiply 1000 by 3 then we get 3000

Therefore 3 kilometres = 3000 meters.

**Example 3. **

Convert 700 centimeters into meters?

**Solution:**

We know that

100 centimetres = 1 meter

700 centimeters = ?

Divide 700 by 100 then we get 7

Therefore 700 centimetres = 7 meters

**Example 4. **

Convert 4000 meters into kilometers?

**Solution:**

We know that,

1000 meters = 1 kilometer

4000 meters = ?

Divide 4000 by 1000 then we get 4

Therefore 4000 meters = 4 kilometres

**Example 5. **

Convert 6 meters into centimeters?

**Solution:**

We know that,

1 meter = 100 centimetres

6 meters = ?

Multiply 100 by 6 then we get 600

Therefore 8 meters = 600 centimetres
