Specified Fuel Consumption (\( SFC \)):

\[ SFC = \frac{Fc \times Pf}{P} \]

Where:

• \( SFC \) is the specified fuel consumption, in grams per kilowatt-hour (g/KW-h).
• \( Fc \) is the fuel consumption, in liters per hour (L/h).
• \( Pf \) is the density of fuel, in grams per liter (g/L).
• \( P \) is the axle or rotary shaft power, in kilowatts (KW).
