How to calculate mass and weight?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
To calculate mass:
- From density: Mass = Density × Volume
- From weight: Mass = Weight ÷ 9.8 (on Earth)
- Direct measurement: Use a balance or scale
To calculate weight:
- Weight = Mass × Gravitational acceleration
- On Earth: Weight (N) = Mass (kg) × 9.8 m/s²
Remember that mass is measured in kg, while weight is measured in Newtons.
