👉 The Kilometers Fluid, often abbreviated as KF, is a unit of measurement primarily used in the United Kingdom and some other Commonwealth countries to quantify liquid fuel volumes, particularly for motor fuels like petrol and diesel. It represents one thousand liters (1,000 cubic meters) and is equivalent to approximately 0.62137 U.S. gallons or 3.785 liters. This unit is particularly useful for fuel suppliers and consumers as it directly correlates with the amount of fuel a vehicle can carry based on its tank capacity, making it a practical and widely understood standard for fuel consumption calculations.
