### What is Length?

Length is the term that is used for identifying the size of an object or thing. Length is a measure of how long or distance an object is. For example measure of chalk piece, duster, pencil, etc. Generally, we use a ruler scale to measure small objects like pens, pencils, etc. The standard unit of length is based on the metric system meters. According to the units of conversion we can convert from meter to millimeters, centimeters, and kilometers.

### Using Decimals in Measurement of Length

Decimal numbers play a vital role in maths. We use decimals every day with length, weight, etc. Decimal numbers are seen in measuring the dimensions accurately. While measuring the length of a table with a meter scale, the length may not be a whole number. In such situations, there will be the use of decimal in measuring the length.
Conversion of units are
1 km = 1000 cm
1 m = 100 cm
1 cm = 10 mm
1 cm = 0.01 m

### Measuring Length in Decimals Examples

Let us learn the use of decimals in measuring the length with the help of the below example problems. Practice the given questions and test your knowledge.
Example 1.
Convert from 125 cm to meters.
Solution:
Given the dimension 125 centimeters.
We have to convert from centimeters to meters.
We know that,
1 meter = 100 centimeters
1 centimeter = 0.01 meters
125 centimeters = 125 × 0.01 meters = 1.25 meters
Thus the conversion from 125 centimeters to meters is 1.25 meters.

Example 2.
Convert from 75 cm to kilometers.
Solution:
Given the dimension 75 centimeters.
We have to convert from centimeters to kilometers.
We know that,
1 centimeter = 0.001 kilometer
75 centimeters = 75 × 0.00001 kilometer = 0.00075 kilometers
Thus the conversion from 75 centimeters to kilometers is 0.00075 km.

Example 3.
Convert from 500 meters to kilometers in decimal.
Solution:
Given the dimension 500 meters.
We have to convert from centimeters to kilometers.
We know that,
1 meter= 0.001 kilometer
500 meters = 500 × 0.001 kilometers = 0.5 kilometers
Thus the conversion from 500 meters to kilometers is 0.5km.

Example 4.
Convert 75 cm to meters into decimals.
Solution:
Given the dimension 75 cm.
We have to convert from centimeters to kilometers.
We know that,
1 meter = 100 centimeters
1 centimeter = 0.01 meters
75 centimeters = 75 × 0.01 meters = 0.75 meters
Thus the conversion from 75 centimeters to meters is 0.75 meters.

Example 5.
Convert 65 mm to centimeters in decimal
Solution:
Given the dimension 65 mm.
We have to convert from millimeters to centimeters.
We know that,
1 millimeters = 0.1 centimeters
65 millimeters = 65 × 0.1 centimeters = 6.5 cm
Thus the conversion from 65 millimeters to meters is 6.5 centimeters.
