weight = (mass) x (gravity)
On the moon, gravity = 1.6 m/s² .
The astronaut, with his mass of 58 kg, weighs
(58 kg) x (1.6 m/s²) = 92.8 newtons (about 21.1 pounds)
On the Earth, gravity = 9.8 m/s² .
The astronaut, with his mass of 58 kg, weighs
(58 kg) x (9.8 m/s²) = 568.4 newtons (about 127.9 pounds)
