Work Step by Step
A pound is a unit of force, showing how much an object weighs on the planet. Gravity on Mars is about 38 percent of what it is on Earth, so a pound of butter on Earth would only weigh 0.38 pounds on Mars.
A kilogram is a unit of mass, and measures how much matter is present. A kilogram of butter on Earth is equal to a kilogram of butter on Mars, or anywhere else in the universe.
