Grade 7 Convert metric units Worksheets

Understanding convert metric units

Converting metric units asks learners in Grades 6 and 7 to change a measurement from one metric unit to another using powers of ten. Because the metric system is built on tens, converting to a smaller unit multiplies and converting to a larger unit divides, by factors such as 10, 100 or 1000. Mastering these exchange rates makes measurement calculations and comparisons straightforward.

For example, 3 km = 3 × 1000 = 3000 m, while 4500 g = 4500 ÷ 1000 = 4.5 kg. A common mistake is multiplying when you should divide, which happens when learners do not notice whether the new unit is smaller or larger. Tip: ask whether you are moving to a smaller unit (you will need more of them, so multiply) or a larger unit (you will need fewer, so divide), and use the correct factor — 1000 for km/m or kg/g and L/mL, 100 for m/cm, 10 for cm/mm.
