Brake Specific Fuel Consumption Calculator
Result
Brake Specific Fuel Consumption Calculator Calculate brake specific fuel consumption (BSFC) — how much fuel an engine burns per unit of power produced. Enter the fuel mass flow rate and the brake power output to see the BSFC, a key measure of engine effic — free online calculator.
Formula
- Brake Specific Fuel Consumption Calculator calculates its result from Fuel Mass Flow Rate, Brake Power Output. It uses the formula BSFC = Fuel Mass Flow Rate ÷ Brake Power. Change any input to recalculate the result instantly.
- The main inputs are Fuel Mass Flow Rate, Brake Power Output. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Brake Specific Fuel Consumption
- Fuel Mass Flow Rate: 20
- Brake Power Output: 75
Using Fuel Mass Flow Rate = 20, Brake Power Output = 75, the calculated result is 0.2666666667.
