Measure mass of objects

Mass

Mass is one of the measurements that allows us to work out how heavy or light things are. In everyday life, there are many things where we need to know, or approximate, the mass of an object or living thing. Sometimes we don't have a way to measure something but we can still make an estimation of the mass.

Some common units of mass are:

• milligrams (mg) for very light things
• grams (g) 
• kilograms (kg) for heavy things

In Video 1, we'll look at some common objects and think about which units of measurement would we useful to use for these objects. You might want to think about some everyday objects and what their mass might be.
