Class 4 GK Worksheet: Units and Measurement
Remember (What are we measuring?): Length: millimetre, centimetre, metre, kilometre. Weight: milligram, gram, kilogram, tonne. Capacity: millilitre, litre. Temperature: degree Celsius. 10 mm = 1 cm, 100 cm = 1 m, 1000 m = 1 km, 1000 g = 1 kg, 1000 mL = 1 L, 1000 kg = 1 tonne, 60 seconds = 1 minute, 60 minutes = 1 hour. Best unit: cities apart – kilometres, a classroom – metres, a pencil – centimetres, a child – kilograms, an eraser – grams, a bucket of water – litres, cough syrup – millilitres.
