How shall I use the Area unit converter?
Select the unit of area you want to convert from, then the unit you want to convert to. Next, enter the area value you want to convert in the box below. The area conversion happens immediately. Our Area 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 area?
Conversion between area 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 square inch to a square centimeter. Let’s take a simple example!
- Let’s say that you want to find out how many square centimeters are 10 square inches. We know that 1 square inch (in²) = 6.4516 square centimeter (cm²) (so this is the conversion rate between square inch and square centimeter). So if you want to calculate how many square centimeters 10 square inches are, you need to do the following:
- You only have to multiply 10 with the conversion rate (i.e. with 6.4516).
- The result 64.516, so 10 square inch (in²) = 64.516 square centimeter (cm²)
OK, but what if you want to make an area conversion in the opposite direction? If you want to convert from square centimeters to square inches, 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 square inches 64.516 square centimeters are.
- Divide 64.516 by 6.4516.
- The result is 10 (square inches).
