I am enrolled in a course related to physics, and converting between mass units is so tricky for me. I always treat in my work only in SI units and maybe MKS units, at level of weights, I find it easy.
But what about the mass conversion between these units:
The first I see is that
kg comes from
kgf.s^2/m comes from
kgf, doesn't it?
I don't understand, how to convert, for example
50 kg to
()kgf.s^2/m; I couldn't affect it by gravity because they are mass units, not weight-mass conversion anymore.
Please help me.
This is my notes from my class, to get the right units of frequency:
Stiffness Mass Frequency tonf/m ton.s^2/m rad/s kN/m ton rad/s N/m kg rad/s kgf/m kgf.s^2/m rad/s
I have always chose the third row to calculate; but maybe in the exam it could come in other units; and I want to understand it.
I don't know if this is so basic that I have to know, but don't get it.
