Select Earth to Venus or Venus to Earth and enter a scale reading in lb or kg. The result is a standard-gravity force equivalent; mass remains unchanged. Gravitational force is also shown in newtons.

Venus Weight Formula
- W_venus: your weight on Venus (same unit as input)
- W_earth: your weight on Earth
- g_venus: surface gravity on Venus, 8.87 m/s²
- g_earth: standard Earth gravity, 9.80665 m/s² (a reference value, not every location’s actual gravity)
The ratio g_venus / g_earth is about 0.904488, so a Venus weight is roughly 90.45% of the matching Earth weight. To go the other direction, divide instead of multiply: W_earth = W_venus / 0.904488. Mass does not change between planets; only the weight (the force gravity exerts on that mass) does.
Reference Values and Quick Conversions
Surface gravity on Venus is close to Earth’s, which makes Venus the most “Earth-like” planet for weight, even though its surface conditions are not.
| Body | Surface gravity (m/s²) | Weight ratio vs Earth |

Example and FAQ
Example. You weigh 165 lb on Earth. Your Venus scale-equivalent weight is 165 × (8.87 / 9.80665) ≈ 149.24 lb. Your unchanged mass is 165 × 0.45359237 ≈ 74.843 kg, giving a Venus gravitational force of about 663.86 N.
Why is Venus weight so close to Earth weight? Venus has about 81.5% of Earth’s mass and a slightly smaller radius. The two effects nearly cancel, leaving surface gravity within about 10% of Earth’s.
Does my mass change on Venus? No. Mass stays the same. Only the gravitational force on that mass changes, which is what a scale reads as weight.
Would a bathroom scale actually work on Venus? An ideal force-sensitive spring scale retains its Earth calibration and shows the lower scale-equivalent reading on Venus. A balance comparing masses gives the same mass. Actual ordinary scales are not designed for Venus’s extreme surface environment.
