Units of Measurement Worksheet

A surf lifesaving club is preparing for a busy beach day. Help Hana and Wiremu check lengths, masses, capacities and times. Show your working and include units in every answer.

Pick the best unit

Choose a sensible metric unit for each measurement: mm, cm, m, km, g, kg, tonnes, mL, L or kL.

1.The rescue board is about 2.7 ___ long. Choose the most suitable unit: mm, cm, m or km.
  • mm
  • cm
  • m
  • km
2.A packed first-aid kit has a mass of about 1.4 ___. Choose the most suitable unit: g, kg or tonnes.
  • g
  • kg
  • tonnes
3.A water container holds 18 ___. Choose the most suitable unit: mL, L or kL.
  • mL
  • L
  • kL

Convert and compare

Use metric relationships carefully. Remember: 1 km = 1,000 m; 1 kg = 1,000 g; 1 L = 1,000 mL.

4.Hana checks a 2.4 km patrol route. Convert its length to metres.
5.A safety jug contains 1.75 L of water. Convert this capacity to millilitres.
6.The club has 3,600 g of snack supplies. Express this mass in kilograms.
7.Order these water supplies from least to greatest capacity: 0.9 L, 850 mL, 1.05 L, 950 mL. Write them all in millilitres first.

Plan the patrol

Now use the measurements to solve practical club problems. Include calculations and units.

8.Wiremu walks 650 m along the beach, returns 650 m, then walks another 1.2 km to the lookout. How far has he walked altogether in kilometres?
9.A drink station starts with 12 L of water. Volunteers pour out 2.4 L, then refill it with 750 mL. How much water is in the station now? Give your answer in litres.
10.A rescue rope is 24 m long. The club cuts it into 6 equal lengths. How many centimetres long is each piece?
11.A board weighs 8.6 kg when dry. After use, it weighs 9.25 kg. By how many grams has its mass increased?
