Units Of Measure
Overview
Every measurement you ever take comes with a unit attached. A length of 2 means nothing until you say 2 what: metres, centimetres or kilometres. The metric system makes life easy because every step up or down is a power of ten, so converting between units is just a matter of multiplying or dividing by 10, 100 or 1000.
In this lesson you will learn the everyday metric units for mass, length, area, volume and capacity, and how to convert confidently between larger and smaller units. You will also meet the trap that catches more students than any other: converting areas and volumes, where the conversion factor must be squared or cubed. Get that one idea right and a whole family of mensuration questions becomes routine.
Objectives
- Use metric units of mass, length, area, volume and capacity in practical situations and convert quantities into larger or smaller units.
