Metric Units of Length522 Plays
Conversions of metric units of length:
1 km = 1000 m
1 m = 100 cm
1 cm = 10 mm
To convert a larger unit of length to a smaller unit of length, multiply.
To convert a smaller unit of length to a larger unit of length, divide.
To compare two different units of length, first convert them to same unit and then compare.
For example, to compare 7 cm and 80 mm, we first convert 7 cm to mm.
7 cm = 7 x 10 mm (As 1 cm = 10 mm)
= 70 mm
Now, we can compare 70 mm and 80 mm.
70 mm is shorter than 80 mm.
So, 7 cm is shorter than 80 mm.
