How mych does the earth weigh?
5.98 X 1024 kilograms
===============About 1.32 X 1025 pounds
Since Pluto's gravitational pull on its surface is only about 6% that of the Earth on its surface, you would weigh 6% of your Earth weight if you were to stand on Pluto's surface. So, to convert your Earth-weight to your Pluto-weight, you have to multiply your Earth weight by 0.06. In this case, if you weigh 125 lbs on the Earth, you would weigh 7.43 lbs on Pluto.
If you weigh 120 pounds on earth, you would weigh 127.2 pounds on Saturn. Your weight on Saturn is 1.06 times more than on earth. A person that weighs 120 pounds on Earth would weigh 127 pounds on Saturn. To find out how much a person would weigh on Saturn, simply multiply that person's weight by 1.066.
