What is the weight of earth?

Question

What is the weight of earth?

Answer 1

You need mass, not weight.  Weight is a measure of force relative to another more massive object (like human compared to gravity of earth).

5.9736×1024 kg

Answer 2

I love these kind of questions in the Geology section!

Earth's Weight (Mass): 5.972 sextillion (1,000 trillion) metric tons. That's 5,972,000,000,000,000,000,000 tons! Actually, scientists prefer to refer to this measurement as the Earth's mass instead of weight since weight is the result of Earth's gravitational pull on another object. And the Earth cannot pull on itself! As the Earth orbits the Sun, it is weightless. If the Earth were placed on the Sun, it would weigh more than if it were placed on Jupiter, the largest planet in the solar system but much smaller than the sun. Yet, Earth (or any other object for that matter) would have the same mass regardless of where it is located.

New measurements of the weight of planet Earth have taken physicists a step closer to their holy grail: a precise value for the Newtonian gravitational constant.

Earth weighs in at 5.972 sextillion (5,972,000,000,000,000,000,000) metric tons. While this is just a shade under the current textbook estimate of 5.98 sextillion metric tons, it could make all the difference to nailing down the gravitational constant, or Big G.

Newton's gravitational constant tells how much gravitational force there is between two masses -- the Earth and sun, for instance -- separated by a known distance.

To make their measurements, the researchers are using a device called a torsion balance that records nearly imperceptible accelerations from the gravitational effects of four 8.14-kilogram stainless steel balls on a 3- by 1.5-inch gold-coated Pyrex plate just 1.5 millimeters thick.

Answer 3

  6 Sextillion 592 quintillion tons.

Answer 4

mass of Earth = 5.9742 × 1024 kilograms

Answer 5

Weight is a force exerted on a collection of atoms and molecules resulting from their mutual attraction as a 'body' with the earth's center of gravity.  Because the earth is a sphere, all the forces are opposed and cancelled (taking the whole earth as a body) and the earth weighs approximately zero.  A given mass weighs less on the moon than on earth and mass is constant.  A given mass 'weighs' less near the center of the earth than on its surface.  However, one could determine the equivalent weight of the earth assuming that each cubic foot of matter was weighed at the surface of the earth (or convert the estimated mass of the earth to a weight on the earth's surface).  

Answer 6

It turns out that the value of the atmospheric pressure at sea level, combined with an understanding of the physics of weight and pressure, allows us to answer this question relatively easily.
