Free Mass Calculator - Physics Made Easy
Calculate mass from density and volume, convert between mass units, and understand weight versus mass. Essential for physics, chemistry, and engineering.
Quick Answer
Mass = Density × Volume. 1 kg = 2.205 pounds. Mass is constant; weight varies with gravity (weight = mass × 9.8 m/s² on Earth).
Key Facts about Mass Calculator:
- Mass = density × volume
- 1 kg = 2.205 pounds
- 1 pound = 453.6 grams
- Mass is constant; weight varies

Frequently Asked Questions
Everything you need to know about our mass calculator
How do I calculate mass?
Mass = Density × Volume (m = ρ × V)
Mass = Density × Volume. If water (density 1 g/cm³) has volume 500 cm³, mass = 1 × 500 = 500 grams. Or use M = Force / Acceleration for physics problems.
What is the difference between mass and weight?
Mass is matter amount (constant); weight is gravitational force (varies)
Mass is the amount of matter (constant everywhere). Weight is gravitational force on that mass (varies by location). On Earth, weight (N) = mass (kg) × 9.8.
How do I convert kg to pounds?
1 kg = 2.205 lbs (multiply kg by 2.205)
Multiply kilograms by 2.205 to get pounds. 10 kg = 22.05 lbs. To convert pounds to kg, divide by 2.205 or multiply by 0.4536.
