3 feet make 1 yard.

In many parts of the world the units named below are used. These were

used in our country also until these were replaced by metric units after
independence.

Measurement of Length

Length is usually measured in metre. Longer distances are measured in

kilometres and smaller lengths in centimetres.

Metre is the standard unit of measurement of length. But when we have to

measure either shorter length or longer length (distance) we also use two

specific types of units.

Centimetre (cm) for shorter length.

Kilometre (km) for longer length.

100 cm = 1 m

1000 m = 1 km
