Units for measuring length are discussed here.

We have different units of measure to measure lengths. The larger unit of length is kilometers. Smaller units of measurement are decimeters, centimeters and millimeters.

We know that is the standard unit of length ‘Meter’ which is spelled as ‘m’ for short.

One meter in length is divided into 100 equal parts.

Each part is called a centimeter and is abbreviated as “cm”.

So 1 m = 100 cm and 100 cm = 1 m

The long distances are measured in kilometers. This kilometer corresponds to 1000 meters. The kilometer is briefly written as km.

1 kilometer (km) = 1000 meters (m) and 1000 m = 1 km

The various units of length and their equivalents are given here:

1 kilometer (km)

1 hectometer (hm)

1 Demeter (dcm)

1 meter (m)

1 decimeter (dm)

1 centimeter (cm)

= 10 hectometers (hm) = 1000 m

= 10 decathletes (dcm) = 100 m

= 10 meters (m)

= 10 decimeters (dm) = 100 cm = 1000 mm

= 10 centimeters (cm)

= 10 millimeters (mm)

Most of the time we use kilometers (km), meters (m) and centimeters (cm) as units of length.

If you look at the ruler, you can see that one centimeter is divided into 10 equal parts, indicated by smaller lines. Each line stands for 1 millimeter. So 10 millimeters correspond to 1 cm. 10mm = 1cm.

Units for measuring length

Millimeter is written in abbreviated form as mm. Smaller lengths such as the thickness of a tile or cardboard are measured in millimeters.

If we divide 1 meter into 10 equal parts, each part is called a decimeter. It is written in short form as dm.

10 dm = 1 m

The higher unit of measure for length is kilometers. We already know that 1 kilometer = 1000 meters.

Standard length units

Note: The set of standard units we use is known as the metric system.

To convert kilometers to meters, we multiply by 1000 and we divide meters to kilometers by 1000.
