Quick Reference
How it works
A weight calculator converts between units of weight and relates weight to mass via gravity. Weight is the force gravity exerts on mass (weight = mass × g), which is why the same mass weighs less on the Moon than on Earth.
Weight & conversions
Weight = mass × g 1 kg ≈ 2.205 lb
- mass
- amount of matter (kg)
- g
- gravity ≈ 9.81 m/s² on Earth
Worked example
- Convert 70 kg to pounds
- 70 × 2.205
≈ 154.3 pounds.
Good to know
- Mass stays constant; weight changes with gravity (lower on the Moon, higher on Jupiter).
- Everyday 'weight' in kg is really mass — true weight is a force measured in newtons.
- Convert pounds to kilograms by dividing by 2.205.

How do I calculate my BMI?
BMI = weight in kilograms divided by height in meters squared. A 70 kg person at 1.75 m has a BMI of 22.9. Standard categories: under 18.5 underweight, 18.5-24.9 normal, 25-29.9 overweight, 30+ obese.
What is a safe rate of weight change?
About 0.5-1 kg (1-2 lb) per week is the widely recommended sustainable pace, which corresponds to a daily calorie deficit or surplus of roughly 500-1,000 kcal. Faster crash approaches tend to sacrifice muscle and rebound.
