Length is measured in various units such as Kilometer, Hectometer, Decameter, Meter, Decimeter, Centimeter, and Millimeter.

An easy and interesting way to remember this is the following statement.

King Harry Died Mother Didn`t Cry Much.

The ‘M’ in Mother stands for METER.

Meter is the standard unit of length.

Between 2 units there is a jump of 10. Kilometre or km is the largest unit of length. Millimetre or mm is the smallest unit.

While Converting From a Larger Unit to a Smaller Unit, We Multiply

For Example:

1. km → m

1 km = 1000 m

Therefore, 3 km = 3000 m

2. m → cm

1 m = 100 cm

Therefore, 5 m = 500 cm

3. hm → dm

1 hm = 1000 dm

Therefore, 15 hm = 15000 dm

While Converting From a Smaller Unit to a Larger Unit, We Divide

For Example:

1. mm → cm

1 mm = 1/10 cm

Therefore, 2 mm = 2/10 cm

2. dm → dam

1 dm = 1/100 dam

Therefore, 7 dm = 7/100 dam

3. cm → m

1 cm = 1/100 m

Therefore, 7.5 cm = 7.5/100 m
