On Venus, you would weigh 90.4% of your weight on Earth. Multiply your Earth weight by 0.904: a 70 kg person would read 63.3 kg, and a 154 lb person 140 lb. That is 9.6% lighter than on Earth. Your mass does not change; only the pull on it does.
The surface gravity is 8.87 m/s² against 9.81 m/s² on Earth. Weight is mass times local gravity, W = m × g, so the scale reading is your Earth reading times 0.904.
Weight on Venus by Earth weight
Each row is a person’s Earth weight and what the same person reads on Venus. The pounds column converts the kilograms (1 kg = 2.20462 lb); the ratio 0.9042 is the same for any unit.
| On Earth | On Venus (kg) | On Venus (lb) |
|---|---|---|
| 40 kg (88.2 lb) | 36.2 kg | 79.7 lb |
| 50 kg (110 lb) | 45.2 kg | 99.7 lb |
| 60 kg (132 lb) | 54.3 kg | 120 lb |
| 70 kg (154 lb) | 63.3 kg | 140 lb |
| 80 kg (176 lb) | 72.3 kg | 159 lb |
| 90 kg (198 lb) | 81.4 kg | 179 lb |
| 100 kg (220 lb) | 90.4 kg | 199 lb |
Calculated as weight × 8.87 ÷ 9.81. A bathroom scale calibrated on Earth would show these values.
Why gravity is 8.87 m/s² on Venus
Surface gravity follows from the body’s mass M and its radius R: g = G M ÷ R². The simulation uses a radius of 6,052 km, which with g = 8.87 m/s² corresponds to a mass of 0.815 Earth masses.
Venus is almost Earth’s twin in size, about 95% of its diameter, and its surface gravity is 90.4% of ours. The numbers on this page are the easy part: the air at the surface is about 92 times Earth’s pressure and around 465 °C, so you could not stand there to feel the weight.
The pull on Venus is the same as at the cloud tops of Uranus, 8.87 m/s², even though one is a rocky planet and the other a gas giant. Gravity depends on mass and radius together, and the two cancel out differently in each case.
A jump and a fall on Venus
Gravity sets more than weight. The take-off speed that lifts you 50 cm on Earth would raise you 55.3 cm on Venus, in a jump lasting 0.706 s against 0.639 s on Earth. A ball dropped from 2 m takes 0.672 s to land, compared with 0.639 s on Earth.
Escape speed, the speed at which you leave for good, is 10.4 km/s, against 11.2 km/s for Earth. It does not depend on your mass.

Frequently asked questions
How much does a 70 kg person weigh on Venus?
63.3 kg (140 lb). The ratio to Earth is 0.904, from g = 8.87 m/s² against 9.81 m/s².
Does my mass change on Venus?
No. Mass is the amount of matter in you and stays the same everywhere. Weight is the force gravity puts on that mass, so it is the weight that changes, to 90.4% of its Earth value.
How do I work out my weight on Venus?
Multiply your Earth weight by 0.904. In kilograms or pounds the answer comes out in the same unit, because the ratio has no unit.
How high could I jump on Venus?
A jump that rises 50 cm on Earth would rise 55.3 cm on Venus, because height scales as 1 ÷ g for the same take-off speed.
