Introduction to Measurement Units
Help plan a class picnic by choosing sensible metric units and converting between them. Show your working where needed.
Pick the right unit
Choose the most suitable unit for each item. Think about whether you are measuring length, mass or capacity.
1.A picnic rug is about 2 long. Which unit makes the most sense: millimetres, centimetres or metres?
2.A bag of apples has a mass of about 2. Which unit is most sensible: grams or kilograms?
3.A drink bottle holds 750. Which unit belongs after the number: millilitres or litres?
Convert for the picnic
Use these facts: 1 m = 100 cm; 1 kg = 1,000 g; 1 L = 1,000 mL.
4.The picnic table is 1.6 m long. How many centimetres is that?
5.A watermelon has a mass of 2,500 g. Write its mass in kilograms and grams.
6.The drink dispenser contains 3 L of water. How many millilitres is that?
Solve the picnic puzzles
Use metric units in your answers. Show how you worked it out.
7.A 2 L bottle is poured into cups that each hold 250 mL. How many full cups can be filled?
8.A rope is 3 m long. Arjun cuts off 85 cm. How much rope remains? Give your answer in centimetres.
9.The fruit basket has 1 kg 750 g of oranges and 850 g of mandarins. What is the total mass in kilograms and grams?
10.A cooler has a capacity of 5 L. It already contains 3,250 mL of water. How many more millilitres can it hold?
