The formula is: Relative Centrifugal Force (RCF or G-value) = (11.18) x ( r ) x (n x n) x (10^{-6}) Where: r = Centrifugal radius in cm (distance between rotational center and sample center); and n = revolutions per minute So, for example: If the radius were 10 cm, and the revolutions were 1900, the G force would be: (11.18) x (10) x (1900 x 1900) x (10^{-6}) or: (11.18) x (10) (3,610,000) x (10^{-6}) or: (403,598,000) x (10^{-6}) or: about 403.6 G. | To make life easier, we have included a centrifugation calculator to do the math for you!
