What is weight of a 60kg astronaut on earth?

The weight of an object is calculated using the formula ( \text{Weight} = \text{mass} \times \text{gravity} ). On Earth, the acceleration due to gravity is approximately ( 9.81 , \text{m/s}^2 ). Therefore, a 60 kg astronaut would weigh ( 60 , \text{kg} \times 9.81 , \text{m/s}^2 ), which equals about 588.6 newtons.
