Example: Flying at 25.1" MP, 2400 RPM, 2200 ft and at 75° F outside air temp the engine should produce 139 Hp on a standard day (HPs). However, the inlet air is 25° F higher than standard day (75° F vs. 50° F), so we must correct for this by multiplying HPs by the square root of the temperature ratio (adjusting for absolute, or Rankine, temperature).

Thus, 139x [(460+50)/(460+75)]^0.5 = 135.7 HP actual.
