Conversion of units:

Based on the conversion of units for lengths, studied earlier, the units of areas can also be converted:

  • Kilometres, metres, centimetres, millimetres are units of length.
  • 10 millimetres = 1 centimetre
  • 100 centimetres = 1 metre
  • 1000 metres = 1 kilometre

  • Unit Conversion
    1 cm2 100 mm2
    1 m2 10,000 cm2
    1 ha 10,000 m2

Example

Convert the following: 50 cm2 in mm2

50 cm2 in mm

= 100 x 50.......(1 cm2 = 100 mm2)

= 5000 mm2

Example

Convert the following: 2 ha in m2

2 ha in m2

= 2 x 10000..........(1 hectare = 10000 m2)

= 20,000 m2

Example

Convert the following: 10 m2 in cm2

10 m2 in cm

= 10 x 10,000........(1 m2 = 10,000 cm2)

= 100,000 cm2.
