What is the formula to calculate fuel consumption in main engine of ship?

The formula to calculate fuel consumption in the main engine of a ship is:

[ \text{Fuel Consumption (kg/h)} = \frac{\text{Power Output (kW)} \times \text{Specific Fuel Consumption (SFC, kg/kWh)}}{1000} ]

Where the Specific Fuel Consumption (SFC) is the amount of fuel consumed per unit of power produced, typically expressed in kilograms per kilowatt-hour (kg/kWh). This formula helps in estimating the fuel needed based on the engine's power output and efficiency.
