According to the length conversion charts, units of lengths and their equivalents are:

1 kilometre (km) = 10 Hectometres (hm) = 1000 m

1 Hectometre (hm) = 10 Decametres (dam) = 100 m

1 Decametre (dam) = 10 Meters (m)

1 Meter (m) = 10 Decimetres (dm) = 100 cm = 1000 mm

1 Decimetre (dm) = 10 Centimetres (cm)

1 Decimetre = 0.1 Meter

1 Centimetre (cm) = 10 Millimetres (mm)

1 Centimetre = 0.01 Meter

1 Millimetre = 0.001 Meter

Note:

1 mile = 1760 yards

1 mile = 5280 feet

1 yard = 3 feet

1 foot = 12 inches

Conversion

While converting from a larger unit to a smaller unit, we multiply

Example 1:

km → m

1 km = 1000 m

Therefore, 5 km = 5 x 1000 = 5000 m

Example 2:

m → cm

1 m = 100 cm

Therefore, 4 m = 4 x 100 = 400 cm

Example 3:

hm → dm

1 hm = 1000 dm

Therefore, 20 hm = 20 x 1000 = 20000 dm

While converting from a smaller unit to a larger unit, we divide

Example 1:

mm → cm

1 mm = 1/10 cm

Therefore, 20 mm = 20/10 cm = 2 cm

Example 2:

dm → dam

1 dm = 1/100 dam

Therefore, 300 dm = 300/100 dam = 3 dam

Example 3:

cm → m

1 cm = 1/100 m

Therefore, 150 cm = 150/100 m = 1.50 m
