Units for Measuring Length

Units for measuring length are discussed here.

We have different units of measurements to measure lengths. The bigger unit of measuring length is kilometer. Smaller measurement units are decimeter, centimeter and millimeter.

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

A meter length is divided into 100 equal parts.

Each part is named centimeter and written in short as ‘cm’.

Thus, 1 m = 100 cm and 100 cm = 1 m

The long distances are measured in kilometer. This kilometer equals to 1000 meters. The kilometer is written in short as km.

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

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

1 kilometer (km)

1 Hectometer (hm)

1 Demetre (dcm)

1 Meter (m)

1 Decimeter (dm)

1 Centimeter (cm)

= 10 Hectometers (hm) = 1000 m

= 10 Decathletes (dcm) = 100 m

= 10 Metres (m)

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

= 10 Centimetres (cm)

= 10 Millimetres (mm)

Mostly we use Kilometer (km), Meter (m) and Centimeter (cm) as the units of length.

If you look at the ruler you can find that one centimeter is divided into 10 equal parts which are marked by smaller lines. Each line represents 1 millimeter. So, 10 millimeters is equal to 1 cm. 10 mm = 1 cm.

$Units for Measuring Length$

Millimeter is written in short form as mm. Smaller lengths such as thickness of a tile or card board are measured in millimeters.

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

10 dm = 1 m

The higher unit to measure the length is kilometer. We know already that 1 kilometer = 1000 meters.

$Standard Units of Length$

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

To convert kilometer into meters we multiply by 1000 and meters into kilometer we divide by 1000.
