Class 7 Maths Perimeter and Area Conversion of Units

Conversion of Units

Conversion of units is the conversion between different units of measurement for the same quantity.

Here, we convert different units while measuring areas to another unit.

We know that 1 m = 100 cm

Now 1 m2 = 1 m * 1 m

                   = 100 cm * 100 cm = 10000 cm2

1 km = 1000 m

1 km2 = 1 km * 1 km

            = 1000 m * 1000 m

            = 1000000 m2

1 hectare = 10000 m2

100 cm = 1 m

1 cm = 1/100 m

1 cm2 = 1 cm * 1 cm

           = 1/100 m * 1/100 m

           = 1/10000 m2  

1000 cm2 = 1000/1000 m2 = 0.1 m2
