How to Convert Units of Length 
The metric system involves a unit of length as the meter. There are smaller and bigger units of length where meter remains the standard unit. The following diagram shows the conversion chart for metric units of lengths: kilometers, meters, centimeters and millimeters.
Here is the display of Common Metric Length Conversions.
Kilometers (km) to Meters (m) ×1000. (Move decimal point 3 to the right).
Meters (m) to Centimeters (cm) ×100. (Move the decimal point 2 to the right).
Meters (m) to Millimeters (mm) ×1000.. (Move decimal point 3 to the right).
Centimeters (cm) to Millimeters (mm) × 10. (Move decimal point 1 to the right).
Millimeters (mm) to Centimeters (cm) ÷ 10. (Move decimal point 1 to the left).
Millimeters (mm) to Meters (m) ÷ 1000. (Move decimal point 3 to the left).
Centimeters (cm) to Meters (m) ÷ 100. (Move decimal point 2 to the left).
Meters (m) to Kilometers (km) ÷ 1000. (Move decimal point 3 to the left).
Notice that to convert from a physically larger unit, such as kilometer (km), to a physically smaller unit, such as meter (m), you always multiply. On the other hand, to convert a measurement in a smaller unit to a larger unit, you always divide. For example, to convert from meters to centimeters, you need to multiply by 100. Where meter is a bigger unit and centimeter is a smaller unit.
