 # Use of Decimal in Measuring the Distance | How do you Measure Distance using Decimals?

A decimal number is a way to express large and small numbers by utilizing the decimal point. The distance like kilometers and meters are expressed in decimal form. We observe the decimal system in our day-to-day life like measuring the objects, distance in centimeters, meters, and kilometers. This article helps the students to 4th grade to learn the use of decimal in measuring distance. And also you will learn about the conversions from meters to kilometers, centimeters to kilometers, etc. Kilometers, meters, and centimeters can be expressed in decimals let us see how to express them by solving the below problems.

### Distance Unit Conversions

Go through the following quick unit conversions of distance and change between one unit to another unit easily. They are as under

• 1 km = 1000 meters
• 1 meter = 0.001 km
• 1 meter = 100 cm
• 1 cm = 0.01 meters
• 1 kilometer = 100000 centimeters
• 1000 cm = 0.01 km
• 1 cm = 0.00001 km

### Using Decimals in Measuring Distance Examples

Example 1.
Convert 12km 270m into kilometres in the decimal form
Solution:
We have to convert from meters to kilometers
1000metres = 1 kilometre or 1000m = km
So, 1m is one thousandths of a km
1m = 1/1000km = 0.001km
270m = 270/1000km = 0.270 km
12km 270m = 12.270km
Thus 12km 270m into kilometers in the decimal form is 12.270 km.

Example 2.
Convert 72km 32m into kilometres in the decimal form
Solution:
We have to convert from meters to kilometers
1000metres = 1 kilometre or 1000m = km
So, 1m is one thousandths of a km
1m = 1/1000km = 0.001km
32m = 32/1000 = 0.032 km
72km 32m = 72.032km
Thus 72km 32m into kilometers in the decimal form is 72.032 km.

Example 3.
Convert 98km 203m into kilometres in the decimal form
Solution:
1000 metres = 1 kilometre or 1000m = km
So, 1m is one thousandths of a km
1m = 1/1000km = 0.001km
203m = 203/1000 = 0.203
98km 203m = 98.203km
Thus 98km 203m into kilometers in the decimal form is 98.203km.

Example 4.
Convert 43km 2m into kilometres in the decimal form.
Solution:
1000metres = 1 kilometre or 1000m = km
So, 1m is one thousandths of a km
1m = 1/1000km = 0.001km
2m = 2/1000 = 0.002
43km 2m = 43.002 km
Therefore 43km 2m into kilometers in the decimal form is 43.002 km

Example 5.
Convert 432km 100m into kilometers in the decimal form.
Solution:
1000metres = 1 kilometre or 1000m = km
So, 1m is one thousandths of a km
1m = 1/1000km = 0.001km
100m = 100/1000 = 0.100km
432km100m = 432.100km
Thus 432km 100m into kilometers in the decimal form is 432.100km

### FAQs on Usage of Decimals in Measurement of Distance

1. Why is it important to use decimals correctly?

Decimals are important because people use them every day in different situations, such as counting money, looking at price tags etc.

2. How do you convert km into a decimal?

1 km = 1000 meters
Now convert from meters to kilometers
1 meter = 0.001 km
Thus the decimal form of the kilometer is 0.001 km.

3. How many km are in centimeters?

Now convert from centimeter to kilometer.
1 kilometer = 100000 centimeters
1000 cm = 0.01 km
