Calculate weight of parachutist?
Mass of parachutist = 75kg
Gravitational field strength = 10 N/kg
What is his weight?
=======
Here's how I done it:
F=mg
m = 75
g = 9.8m/s squared
f = 75 x 9.8m/s squared
Obviously this is wrong, so how do I do it?

don't use the g=9.8 but g=10 as in setup
M=m*g
Newton = kg*m*s^-2 which fits the m [kg] * g [m*s^-2]
