Fuel capacity refers to the maximum amount of fuel that a vehicle or container can hold. This measurement is crucial for determining how far a vehicle can travel before needing to refuel. It is typically expressed in liters or gallons, depending on the region. Understanding fuel capacity helps users plan their trips and manage fuel costs effectively. For example, a car with a larger fuel capacity, like a SUV, can travel longer distances without refueling compared to a smaller vehicle, such as a compact car. This information is essential for both everyday drivers and commercial transport operators.
