CHOKED FLOW EQUATION dimensional units:

The only difference between the the metric units version and the U.S. customary units version is in these terms:

Metric: $Q=A(\rho P)^{1/2}$

U.S.: $Q=A(g_{c}\rho P)^{1/2}$

All of the other terms are dimensionless.

Metric units:

Q = m² [kg/m³ • kg/(m•s²)]^1/2 = m²[kg²/(m⁴•s²)]^1/2 = kg/s

U.S. units:
