if something weighs 180lbs on Earth how much would it weigh on Venus?

163 pounds:)

.907 times your weight equals your weight on Venus

It would also weigh 180lbs on Venus.

Weight = Mass x Gravitational acceleration

Mass is constant no matter where you are, and in the above equation mass should be in the kg unit.

Weight is a function of mass and gravitational acceleration. Gravitational acceleration of Venus is 3.69ms^(-2).

But you gave a mass of 180lbs and seems to be asking for the mass on Venus. The mass would be the same. If when you ask for how much would it weigh on Venus and you expect an answer in either Newtons or kgms^(-2), then you can calculate it based on the above, using 1 lb = 0.45359237 kg

I.e. weight for the same mass on Venus

= 180lb x (0.45359237kg/1lb) x 3.69ms^(-2)

= 301.28 N

or

= 301.28 kgms^(-2)

Note that weight and mass are often used in everyday language as synonymous, but in physics, they are fundamentally different quantities: mass is an intrinsic property of matter, whereas weight is a force that results from the action of gravity on matter.

Since the gravity on Venus is .91 that of the earths gravity, an object weighing 180lbs on earth would appear to weigh

180 x .91 = 163.8 lbs

180 pounds. The use of weight is displaced only by the

quantity of the orbit distress in flight to the 1000th degree. A

scientist that uses scales would not notice the difference.

The surface gravity item for each planet when multiplied times the earth weight will give you the weight on that planet.

174.5 lbs
