What is the body weight if its weight is 50 kg?

m = 50 kg.
g = 9.8 m / s ^ 2.
P -?
The weight of the body P is the force with which the body presses on the support or stretches the suspension. The body presses on the surface with the force of gravity of the earth, with the force of gravity m * g, where m is the mass of the body, g is the acceleration of gravity on the surface of the Earth.
P = m * g.
P = 50 kg * 9.8 m / s ^ 2 = 490 N.
Answer: body weight is P = 490 N.
