We usually centrifuge samples before injecting them onto HPLC. I leart that rpm is no longer an valid unit. Could anyone tell me how to calculate
g-1 from rpm? Many thanks in advance.

The relative centrifugal force (RCF) = .00001118 x r x N^2. Where r is the radius of rotation in cm and N^2 is the square of the speed of rotation in revolutions per minute (rpm).
Thus for a 10cm rotor at 3000rpm:
RCF = .0000118 x 10 x 30000 x 3000 = 1006 g
