Weight(W)=mass(M)* acceleration due to gravity(g) which is =9.8ms^2
therefore,weight of 40kg is
w=40 * 9.8
w=392N
What planet are you on? I don't mean to be a wise-ass, but weight depends upon the acceleration of gravity, which is different on different planets, whereas mass is the same no matter where you are. On the surface of the Earth, the acceleration due to gravity is 9.8 m/s2, so a 40-kg mass will weigh 40 x 9.8 = 392 newtons.
88.185 pounds on earth (rounded)
If a student's mass is 40kg on earth, then his mass is 40kg wherever in the universe he goes. Mass doesn't change. What changes is the gravitational force between each mass and the other masses in the vicinity of the first one. That force is what we call "weight".
40kg = 6st 4.18 pounds.
The 40kg student's force (weight) on Earth is about 392.28 newtons. (Force = mass x acceleration). Earth's acceleration is 9.807 meters per second squared.
40kg of mass, 400 (approx) N of weight.
W = m * g Weight of an object equals the mass of the oject multiplied by the gravitaional constant
You multiply the mass by the gravity. Normal Earth gravity is about 9.8 (in meters/second2, or the equivalent newton/kilogram).
A pound (lb) is a measure of mass which is not the same as weight. An oject with a mass of 2240 pounds on earth would have a mass of 2240 pounds on the moon. But the weight of the object would be only one sixth on the moon. A mass of 2240 lb is equivalent to an Imperial ton.

That's called the mass.
He is 40kg. (88 lbs)
