Weight at any gravity calculator
The general case: give a gravity and a mass and read off the force.
m/s2
m/s2
A lift accelerating upward makes you heavier.

- Mass = 70
- Local gravity = 9.806 65
- Vertical acceleration = 0
- Weight = 70 * 9.806 65 = 686.466
- Apparent weight while accelerating = 70 * (9.806 65 + 0) = 686.466
- Weight in kilograms-force = 686.466 / 9.80665 = 70
- Apparent weight on a scale = 686.466 / 9.80665 = 70
- Weight in pounds-force = 686.466 / 4.4482216152605 = 154.324
- Gravity relative to Earth = 9.806 65 / 9.80665 = 1
- Apparent g-loading = (9.806 65 + 0) / 9.80665 = 1
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- W = m g
- apparent weight = m (g + a)
Standard gravity is defined as exactly 9.806 65 m/s2, so the conversion between newtons and kilograms-force is exact.
