Measurement of Length

Measurement of length is the process of measuring the distance between any two points in term of width, thickness, depth, and height.

Instruments for measuring length are

In the olden days, length is measured using hand span, foot, arms length, pace or stride. These are not accurate form of measurement.

But today, the accurate form of measuring length can be done using the following:

1. Meter Rule
2. Ruler
3. Tape rule

The International System Unit (SI Unit) of measuring length is Meter. Meter is indicated as m.

Other unit of length are centimeter and kilometer.

Metric unit of Length.

10 millimeters (mm) = 1 Centimeter (cm)

10 centimeter (cm) = 1 Decimeter

10 decimeter (dm) = 1 Meter

100 centimeter(cm) = 1 Meter(m)

1000 meter (m) = 1 kilometer (km)
