Class 3 Maths Worksheet: Measurement
The method (Big unit to small: multiply): 1 m = 100 cm, 1 km = 1000 m, 1 kg = 1000 g, 1 L = 1000 mL. Big unit → small unit: multiply. Small unit → big unit: divide. 2 m 35 cm = 200 cm + 35 cm = 235 cm. Choose the unit by size: a pencil in cm, a road in km, a toffee in g, a bucket of water in L.
