Brake-specific fuel consumption (BSFC) is a measure of the efficiency of an engine in converting fuel into energy, specifically in terms of the amount of fuel consumed per unit of power output. It is expressed typically in terms of grams of fuel consumed per kilowatt-hour (g/kWh) or pounds of fuel per horsepower-hour (lb/hp·h).
