Conversion of Metric Units of Length

In this activity we will discuss conversion of metric units of length. We already know that standard metric unit of length is Meter (also written as Metre). Symbol used to denote Meter is "m".

Based on the sizes of lengths we want to measure, we need the derivatives of Meter. For example somebody wants to measure the thickness of human hair or thickness of sheet of a papers. Somebody else wants to measure the distance between two cities. Both of these persons wants to measure lengths but their difference is huge.

Based on the needs and to measure long and large lengths (distances) we use the prefix "kilo-" in front of Meter which means 1000. Hence 1 kilometer (1 km) is equal to 1000 meters.

Similarly to measure small lengths such as thickness of human hair we use the prefix "milli-" in front the meter and "milli-" means One Thousandth (1/1000) . Hence 1 millimeter (1mm) is equal to 1/1000 meter. Or in other words we can write 1 meter is equal to 1000 millimeters.

Below is the activity sheet followed by a worksheet to practice the conversion among the units of length;
