Assuming the input values are in Inches and KC is in KPSI the result should be divided by 400 to get the power in HP units. Assuming the input values are in millimeters and KC is in Mpa (N/mm 2) the result should be divided by 60,000 to get the power in kW. Hence, the final formulas are: P [ H P] = Q × K C 400. P [ k W] = Q × K C 60, 000.
