How To Convert Units of Measurement?

Step 1: Identify the starting unit

The first step is to identify the base unit of measure. This is the unit from which you need to convert to another unit.

E.g.: if you need to convert from feet to inches, then feet should be your base unit.

Step 2: Identify the resulting unit

The next step is to identify the converting unit. It is the unit you want to convert your measurement to.

Step 3: Find the conversion factor

This step is to find the conversion factor from the base unit to the resulting unit.

Say, if you need to convert from kilometer to yard, then your conversion factor will be 1093.61 which means 1 kilometer = 1093.61 yard.

Please check the table of 'Conversion Factors' below:

Step 4: Perform Math

Once you have the based unit, the resulting unit, and the conversion factor, the last step is to perform the basic math.

Here is the calculation to convert from 25 kilometers to yard:

25 Kilometer = 25 * 1093.61 yard = 27,340.25 yards
