Mass Calculator — Frequently Asked Questions
Q1 How is mass calculated from volume and density? ▾
Mass = Volume × Density (m = V × ρ). For example, 2 liters of water with a density of 1 kg/L has a mass of 2 kg.
Q2 What is the difference between mass and weight? ▾
Mass is the scalar quantity of matter in an object and remains constant anywhere in the universe. Weight is the downward gravitational force acting on that mass.
Q3 How do you convert between metric mass and US customary units? ▾
1 kilogram = 1,000 grams = 2.20462 pounds (lbs) = 35.274 ounces (oz). 1 metric ton = 1,000 kg = 2,204.62 lbs.
Q4 What units are used for microscopic atomic mass? ▾
Microscopic particles and atoms are measured in Unified Atomic Mass Units (u) or Daltons (Da), where 1 u = 1.660539 × 10^-27 kg.
