# Length

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
