The weight of a gallon of diesel fuel isn’t constant. It fluctuates based on temperature and the specific blend of the fuel. Generally, it falls within a range of approximately 7.1 to 7.5 pounds per gallon. This translates to a density range of roughly 0.84 to 0.90 kg/L. For most practical applications, an average of 7.3 pounds per gallon is often used.
Understanding fuel weight is critical across several industries. Transportation companies use this information to calculate payloads and ensure compliance with weight restrictions on roads and bridges. Accurate weight estimations are also essential for fuel efficiency calculations and cost projections. Historically, variations in diesel fuel density have led to the development of standardized measurement and compensation procedures within the fuel industry. This ensures fair transactions and facilitates accurate record-keeping for both suppliers and consumers.
