What is Measuring Length?

Measuring of Length of any object includes in our daily life, we always measure the length of the cloth for dresses, wall-length for wallpapers, and many more other tasks.

You all want to know what is measuring length? Measuring length is a measurement of an object in a unit of length by using measuring tools such as scale or ruler.

For instance, the length of a pen can be measured in inches with the help of a ruler.

What is Length?

Length is determined as “Distance between two points” OR “The maximum extended dimension of an object”. Some of the tools used to measure length are Vernier caliper and Tapes.

What is a Unit of Length?

A unit of length refers any arbitrarily chosen and accepted reference standard for measurement of length. In modern use, the most common units are the metric units, which are utilized across the world. In the United States, the U.S. Customary units are also used mostly. For some purposes in the UK & other countries, British Imperial units are used. The metric system is classified into SI and non-SI units.

Units for Measuring Length

According to the metric system, the standard unit of length is a meter (m). Based upon the measuring of length, the meter can be converted into various units like millimeters (mm), centimeter (cm), and kilometer (km). In accordance with the length conversion charts, the different units of lengths and their equivalents are tabulated below:

Units of Length
10 millimeters (mm) = 1 centimeter (cm)
10 centimeters = 1 decimeter (dm)
10 centimeters = 100 millimeters
10 decimeters = 1 meter (m)
10 decimeters = 1000 millimeters
10 meters = 1 dekameter (dam)
10 dekameters = 1 hectometer (hm)
10 dekameters = 100 meters
10 hectometers = 1 kilometer (km)
10 hectometers = 1000 meters
