Stan Why should the coefficient 1.25 be changed when working in S.I. units. Look at how C is used to calculate V. Do a dimensional analysis of the equation V=Z*I*C*W/Rw. Z gravity I dimensionless W force/ 1 gravity Rw dimensionless V force force = gravity * dimensionless * C * ( force/ gravity) / dimensionless canceling out terms it leaves us with : force = C * force Thus C has no units and as a result will not change in a different set of units. Note that T is specified in seconds which is also a metric unit and S is a scale factor with no units. Mark Gilligan
