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.

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.

**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

**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
