Definition of pound/day (Gasoline at 15.5°C) unit

“Pound/day (Gasoline at 15.5°C)” is a mass-flow unit expressing the quantity of gasoline, standardized at 15.5°C (60°F), transported or consumed in one day. It equals one avoirdupois pound of reference-temperature gasoline per 24 hours.

History of pound/day (Gasoline at 15.5°C) unit

The pound originated as an English customary unit of mass, developing from medieval weighing practices and ultimately related to older Roman and continental standards. The day is the conventional 24-hour interval used for rates. Specifying gasoline at 15.5°C reflects petroleum-industry practice: liquid volumes and densities vary with temperature, so a reference temperature enables consistent measurement and trade. The 15°C or 15.5°C standards became widely used in fuel specifications, custody transfer, and engineering tables, while “pound per day” remains useful where imperial mass units are preferred.

Applications of pound/day (Gasoline at 15.5°C) unit

Today, this unit can describe gasoline mass flow in refinery balances, fuel-delivery systems, storage inventories, emissions calculations, and process simulations. For example, a pump rated at 10,000 pounds per day moves that reference-temperature gasoline mass over 24 hours. Engineers may convert it to kilograms per second, gallons per day, or volumetric flow at another specified temperature.
