Title: Converting Length Metric Units
Course: 2024 Math 6° (Reference) > Section: 23 october - 29 october

How to convert metric units.

A meter is the basic unit of length used in the metric system.

A meter can be subdivided into smaller units by dividing it by 10 (dm), by 100 (cm) and by 1,000 (mm); it can also be multiplied times 10 to obtain Dam; times 100 to obtain Hm, and by 1,000 to obtain Km.

The metric system allows for easy conversion between smaller and larger units.

Watch the video :  Examples how to convert between metric Units.

Metric system length units

Copy this table and the example on your math notebook.

The basic unit of measure is in the middle = Meters.

- To the right side you have smaller units:  dm, cm and mm

- To the left side you have larger units of measure : dam, hm and km

For example:

To convert 1.58m  to cm
You can multiply by 100 (10x10) or move the decimal point two spaces to the right.
1.58 m  =  158.0 cm

To convert 2,579 dm to km

You divide by 10,000 (10x10x10x10) or move the decimal point four spaces to the left.
2,579dm = 0.2579km
