How much does Superman weigh?

Question

Superman's ability to fly is attributed to the lower gravity on Earth compared to the gravity on his home planet, Krypton. That is much like a man going on the moon where the gravity is 1/6th that of earth. A man weighing 60 KG on Earth would weigh merely 10KG on the moon.

In Superman's case then, since he can fly (or to be more technically correct - 'leap') much longer distances, his weight should be extremely low.

Answer 1

Your right, his weight should be extremely low. But if he can carry cars and other heavy objects, shouldn't he be dense as well? It doesn't make sense!

Answer 2

Helloooooooo...Superman is fiction...the laws of gravity are real!!

Answer 3

in the 79 movie, he admitted to 225lbs.

Answer 4

Superman clearly has ways of applying acceleration to his body that are unknown to Earth science.

Answer 5

Maybe true, but when we look technically it is not possible because he is able to create such a force by stopping vehicles and he is also able to fly.That means he is lot more than 60kg with lot of strength in his arms

Answer 6

While Superman's ability to leap could be attributed to Earth's gravity being lower than that of Krypton, it has no bearing on his ability to fly. Newtonian physics tells us that objects in the same gravitational field will fall at the same rate no matter what their weight. A man jumping on the Moon could not be said to be 'flying' any more than he could on Earth -the Moon's lower gravity simply allows him to jump higher. In Superman's case, it's not that he weighs exceptionally less than we do (his weight is usually given to be around 200-225 lbs), it is that on Krypton, we would weigh a great deal more, and consequently have greater strength to compensate for that weight (although this is debatable, since his strength and ability to fly are attributed to the effects of our Sun on his physiology -in some storylines, the absence of the Earth's sun causes him to lose all of his powers, to the point of being as helpless as the average human).

Answer 7

Kilograms is mass, not weight.  If a man is 60 kg on Earth, he's 60 kg pretty much everywhere.

Answer 8

Superman weighs about 180 to 185 pounds according to what i have read. he is but his genes are not made the same as us so that is why he has his powers and ability to fly. and earths gravity does not effect his ability to fly the reason they could not fly on krypton is that it did not have a yellow sun which is what gives superman his abilitys

Answer 9

True, but he has the ability to stop cars, trucks, trains,small meteors (the size of Manhatten), so he must have a good bit of mass to stabilise him.

I'd say the ave weight on Krypton was 6000 kg, and and he weighs a measly 200 kg here. That gives him a 30:1 gravity ratio but the inertia of a mule ... and mules are hard to move
