What percentage of Earth’s surface gravity exists at Mars’s surface?

Mars’s surface gravity is about 38 percent of Earth’s surface gravity.

Mars is smaller and less massive than Earth, so its gravitational pull is weaker. A person who weighs 100 kilograms-force on Earth would weigh roughly 38 kilograms-force on Mars, although their mass would remain unchanged.

This lower gravity affects spacecraft operations, dust movement, atmospheric retention, and the height of a jump. It is strong enough to hold a thin atmosphere and two small moons, but much weaker than Earth’s gravity.

The figure is sometimes confused with Mars’s atmospheric pressure, which is also much lower than Earth’s. Gravity is measured in metres per second squared: Mars’s surface value is about 3.71 m/s², compared with Earth’s approximately 9.81 m/s².
