Calculate engine horsepower and kilowatts from torque and RPM measurements
How to use: Calculate engine power output from torque and RPM measurements. Enter Torque (rotational force - pound-feet or Newton-meters). Enter RPM (engine speed - revolutions per minute at peak torque, typically 3000-6000 RPM). Results show: Horsepower (HP - standard power unit) and Kilowatts (kW - metric power unit). Formula: HP = (Torque × RPM) ÷ 5,252. Conversion: 1 HP = 0.746 kW. Typical values: Economy cars 100-150 HP, Sedans 150-250 HP, Performance cars 300-500 HP, Sports cars 500+ HP. Higher torque at low RPM = better acceleration. Higher HP at high RPM = better top speed. Essential for performance comparisons, engine tuning, and understanding power delivery characteristics.
