How shall I use the Length unit converter?
Select the unit of length you want to convert from, then the unit you want to convert to. Then enter the length value you want to convert in the box below. The length conversion happens immediately. Our Length Conversion Calculator works in both directions: If you enter a value in the other field, it can also change the unit back from it. You can also decide how many decimal places you would like to see in the result.
How shall I convert between units of length?
Conversion between length units usually involves a simple multiplication or division. You only have to know the correct conversion rate. This piece of information is enough to be able to convert 1 mile to km. Let’s take a simple example!
- Let’s say that you want to find out how many miles are 4 kilometers. We know that 1 kilometer (km) = 0.6214 mile (mi) (so this is the conversion rate between mi and km). So if you want to calculate how many miles 4 kilometers are, you need to do the following:
- You only have to multiply 4 with the conversion rate (i.e. with 0.6214).
- The result 2.4855, so 4 kilometer (km) = 2.4855 mile (mi)
OK, but what if you want to make a length conversion in the opposite direction? If you want to convert from miles to kilometers, you have to use the conversion rate mentioned above. Yet, this is the opposite direction, so instead of multiplication, we use the conversion rate for division. In this example it means:
- You would like to know how many kilometers 2.4855 miles are.
- Divide 2.4855 by 0.6214.
- The result is: 4 (km).
