Hello guys from Physics Forums... I got a little problem here..

"Weight of a 60kg man in kgf if the local gravity is 9.6m/s^2"

I got no idea what to do..
I tried 60x 9.6m/s^2
but my teacher said that it was wrong...
I'd really appreciate any help I'll get
and thank you in advance..

Weight=Mass*Acceleration due to gravity=m*g
Assuming 60kg weight at 9.8 m/s^2 calculate mass m(60/9.8=6.122)). This will give mass.Now multiply mass by 9.6 to get kgf or weight for that place(6.122*9.6=58.775). Use results in significant figures if needed.

That gives you the weight in newtons. To convert from newtons to kgf, use: 1 kgf = 9.80665 N

So that's how you get the unit KGF..
now I understand more :) thanks a lot! Doc Al & 1994Bhaskar ^_^

so more likely it's
9.6/9.8x60=58.8kgf

problem [SOLVED]
admins/mods you can close the thread now if you want ^_^
