Damping Coefficient - Calculation, Values, FAQ

WebWhat are the units of damping coefficient? In Imperial units, damper velocities are usually in inches/s and forces in lbf, so the natural unit of damping coefficient is the lbf s/inch, which is a practical size of unit. The lbf s/ft is also usable, but rarer, and reduces to slug/s, although rarely expressed in the latter form.
