No, 20kg of lead and 20kg of feathers would have the same mass in vacuum since both are 20kg. Gravity does not affect mass.
20kg is equal to 20,000g.
On Earth, 20kg is 196 newtons or 44.1 lbs.
10-20kg is equivalent to 22-44 pounds.
The weight of a 20kg box on Earth is approximately 196.2 Newtons. This is calculated by multiplying the mass (20kg) by the acceleration due to gravity on Earth (9.81 m/s^2).
