What is the weight of a 57 kg person on earth?

Answer 1

On Earth, 65 kg of mass weighs 637.5 newtons (143.3 pounds). (both rounded)

Answer 2

The simple answer: about 490 Newtons (50 [kg] x 9.8 [m/s^2] = 490 [N]) by virtue of the relationship F=ma where F is force, m is mass and a is acceleration (in this case, the acceleration due to gravity).

Technically, your weight on earth depends on where on the earth's surface you are located. The reason being that the acceleration due to gravity (often denoted as little g) is not uniformly 9.80 m/s^2 at all places on the earth, due to factors such as altitude and air pressure, and less importantly, humidity and occasionally electric and magnetic disturbances, among others. However, a=9.80 m/s^2 is a good approximation for g (the English equivalent being approximately 32 ft/s^2).

Remember, this only works for weight on earth. Other planets or objects in space will have different accelerations due to gravity.

Answer 3

Since earth's gravity pulls at 1G, they would weight 50kg. While mass is constant, weight is not... conveniently (by design) earth's gravity is such that weight and mass should be equal on our own planet.

Answer 4

The weight of a 57 kg person on Earth would be approximately 560 Newtons, assuming standard gravity of 9.81 m/s^2.

Answer 5

On Earth, 65 kg of mass weighs 637.5 newtons (143.3 pounds). (both rounded)

Answer 6

On Earth, gravity is about 9.8 newton/kilogram, so you can multiply the mass (in kilograms) by 9.8, to obtain the weight (in newton).

Answer 7

On Earth, 57kg is 558.6 newtons or 126 lbs.

Answer 8

The person's weight or force is 637 newtons or 143.3 lbs.

Answer 9

A mass of 65 kg weighs 637 newtons (143.3 pounds) on earth. (rounded)

Answer 10

A person cannot weigh 50 kg since the metric unit of weight is a Newton, not a kg. Consequently the question makes no sense.
