How much does the earth weigh?

Technically speaking, the earth weighs nothing because the weight depends on the force of gravity that acts on the object. The Earth is floating in space.

Nevertheless, mathematicians, as a curiosity, calculated the weight of the earth on the basis of the Earth’s gravitational attraction. They calculated a figure in the region of 6,000,000,000,000,000,000,000,000 kg. In other words, it is about 6 quadrillion kilograms.
