- Make every measurement the SAME unit before using a formula
- Learn the three length conversions: 10 mm = 1 cm, 100 cm = 1 m, 1000 m = 1 km
- For AREA, square the number (e.g. 1 m² = 100² = 10,000 cm²)
- For VOLUME, cube the number (e.g. 1 m³ = 100³ = 1,000,000 cm³)
- Know off by heart: 1 litre = 1000 cm³
Formula used
1 m = 100 cm
1 m² = 100² cm² = 10 000 cm²
1 m³ = 100³ cm³ = 1 000 000 cm³
