How many BTUs are contained in one US gallon of oil?

One US gallon of oil contains approximately 140,000 BTUs (British Thermal Units). This measurement is crucial in various fields, particularly in heating, energy calculations, and when evaluating the efficiency of heating fuels. Understanding the energy content of oil helps in comparing it with other energy sources and determining the appropriate usage for heating systems.

This figure is based on standard industry practices and the chemical characteristics of heating oil, which make it a valuable fuel for residential and commercial heating. Knowing this value enables technicians and engineers to make informed decisions regarding fuel selection and system design to optimize efficiency and performance in heating applications.
