To convert volume to weight, you need to know the density of the substance. Density is the mass per unit volume.
Weight = Volume × Density
For example, the density of water is approximately 1000 kg/m³. If you have 20 liters (0.02 m³) of water, the weight would be:
Weight = 0.02 m³ × 1000 kg/m³ = 20 kg
9.3. Using Dimensional Analysis
Dimensional analysis is a powerful technique for ensuring that conversions are performed correctly. This method involves tracking the units of measurement throughout the calculation to ensure that they cancel out properly.
For example, to convert 20 kg to pounds:
20 kg × (2.20462 lbs / 1 kg) = 44.0924 lbs
