Follow the named arrows: enter the measured quantity, then the vehicle or fleet rate applied across that rectangle.
Horsepower = torque (lb-ft) × RPM ÷ 5,252.
The torque equation assumes simultaneous torque and engine-speed measurements. Drivetrain loss is only a planning assumption; chassis dynamometer methods, correction standards, weather, and equipment produce different results.
