Conversion of Units

Definition - What does Conversion of Units mean?

Conversion of Units is a multi-step process that converts units of measurement for the same quantity. It includes division or multiplication by a numerical factor or rounding off the significant digits. These are important because the units are used in various places such as the commercial marketplace, technical documents, temperature, and for other specifications. A common conversion table states the length, volume, mass, and area. The units are expressed by using scientific notation and converted into numerical values as per the quantities.
