Let's review the units of mass that we already know by trying this practice problem.
It is most appropriate to use milligrams to measure:
Milligrams are appropriate to measure tiny very light objects like a small feather and insects.
Grams are appropriate to measure small light objects like a pencil case or cup.
Kilograms are appropriate to measure heavy objects like people and bikes.
This video introduces the units of milligrams, grams, kilograms and tonnes and discusses the types of objects that would be measured by these units.
Choose the most appropriate unit of measure for the mass of a biscuit.
