Choosing the Correct Measurement Tool

There are several different types of measuring tools that are used to find

• length (some common metric units are mm, cm, m, and km)
• mass (some common metric units are g and kg)
• volume (some common metric units are mL and L)

It is important to select the proper tool in order to obtain a correct or accurate measurement. The accuracy of a measurement is determined by how close a measured value is to the actual value.
