Converting of area units

The conversion between two area measurements is given by:

area_{to}=area_{from}*F

where F is the conversion factor given by:

F=frac{unit_{from} converted to m^2}{unit_{to} converted to m^2}

The conversion factor is the relationship between the two area units, you are converting between. In order to find this relationship both units must be comparable, that is, they must be of the same unit, which could be a base unit like meters or yards.

So if you just know the given units’ relationships to the base units, you will be able to
convert between them.


Example


We want to convert 0,23 dm2 to cm2.

According to the tables below

1 cm2 = 0,0001 m2

And

1 dm2 = 0,01 m2

In order to do the conversion of the area from dm2 to cm2, we need to find the conversion factor, which is the relationship between the two units.

F=frac{0,01}{0,0001}=100

Now you just need to multiply the original area measurement by the conversion factor:

0,23 dm2 converted to cm2 is then:

0,23 dm2 = 100 x 0,23 = 23 cm2
