Because of lower gravity, a person who weighs 220 lbs on Earth would weigh 84 lbs on Mars.

Earth Has More than Double Mars' Gravitational ForceForce

The gravity on Mars' surface is much lower than it is on Earth -– 62% lower to be exact. At just 0.38 of the Earth standard, a person who weighs 100 kg (220 lbs) on Earth would weigh just 38 kg (84 lbs) on Mars.

How much would a 200lb person on Earth weigh on Mars?

76 lb

This question appears to have been merged with something asked about mass and Moon. The 200 lb person on Earth probably weighs 76 lb on Mars.

On Earth, the weight of a 50 kg person is 110 lbs, because that is the force of gravity here. On Mars, their weight will be 0.38 times their Earth weight, or 41.8lbs.
