Best Answer: Mass of earth = 5.9742 Ã 10^24 kilograms. To Calculate, Force of gravity F = G.m1.m2 / r^2. where m1 and m2 are two masses, and G is gravitational constant and r is distance. let m1 = M (mass of the Earth) So, F = G.M.m2 / rÂ². Now, assume m2 is a mass on the surface of the planet.
In the usual units, the mass of something on earth has the same numerical value as its weight on earth. Anything which weighs 150 lbs. on earth will have a mass of 150 lbs. If you ever take a physics course they will try to set up separate units for mass and weight, but it can be confusing.
