mechanical ohm

(mechanics) A unit of mechanical resistance, reactance, and impedance, equal to a force of 1 dyne divided by a velocity of 1 centimeter per second.

acoustics (Metric) Originally coined in a general mechanical context as a parallel of the ohm used for electric impedance,
[Firestone F. A. J. Acoust. Soc. Amer. Vol. 4, 249-56 (1933)] a unit for the mechanical impedance to sound waves. Quantitatively, at a given surface, it is the ratio of average effective pressure (i.e. force) to the volume velocity (i.e. area times speed orthogonally thereto) of the resulting waves through it (but compare acoustic ohm
[Kennelly A. G., Cook J. H. J. Acoust. Soc. Amer. Vol. 9, 336-40 (1938)]). E.g.

Metric-m.k.s. N·(m^-1·s¹) = N·s·m^-1 = m·kg·s^-1.

Metric-c.g.s. dyn·(cm²·cm·s^-1)^-1 = dyn·s·cm^-1 = cm·g·s^-1.

Called also mechanic ohm and, for the latter, mechanic abohm.
