Length Units: Meter, Centimeter, Kilometer

Study Notes

Length Units

In this section, we will discuss three length units commonly used throughout the world: المتر (meter), السنتيمتر (centimeter), and الكيلومتر (kilometer).

المتر (Meter)

The meter is the base unit of length in the International System of Units (SI). It is defined as the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458 of a second.

السنتيمتر (Centimeter)

A centimeter is one hundredth of a meter. It is defined as equal to 1/100 of a meter.

الكيلومتر (Kilometer)

A kilometer is equal to 1000 meters. It is widely used to measure distances between geographical locations, such as the distance between two cities or the distance between a specific location and a landmark.

Conversions

Here are some conversions between the length units we discussed:

1 centimeter is equal to 0.01 meters.
1 meter is equal to 100 centimeters.
1 kilometer is equal to 1000 meters.

Usage in Daily Life

These length units are used in daily life to measure various distances, such as the height of a person, the length of a room, and the distance between two locations. They are also used in scientific measurements, engineering projects, and geographical surveys.
