British Thermal Units (BTU) are a measure of the heat content of fuels or energy sources. They are used to compare different energy sources or fuels by converting their physical measurements (volume or weight) into a common unit of heat content. For example, the heat content of fossil fuels consumed in the United States in a given year can be measured in BTU. One gallon of diesel fuel or heating oil with a sulfur content of less than 15 parts per million contains 137,381 BTU. This information can be used to compare the average fuel prices of different energy sources over a given period.

BTU definition and usage
BTU, or British Thermal Unit, is a unit of measurement that shows how much energy a heating or cooling unit uses to add or remove heat from a space. It is a standard unit for the measurement of heat energy, and one BTU is the quantity of heat required to raise the temperature of one pound of liquid water by one degree Fahrenheit. In other words, it is approximately the amount of energy released by burning a match. BTUs are used to rate energy transfer for air conditioners, heat pumps, furnaces, cooking devices, and other heating and cooling appliances.
BTUs are particularly useful for comparing the efficiency of different energy sources or fuels. For example, the heat content of fossil fuels consumed in the United States in a given year can be converted into their Btu equivalent to allow for easy comparison. This is especially relevant when comparing the average fuel prices of natural gas and heating oil, which can be done by dividing the average monthly prices by the Btu content of the fuels.
In the United States, BTU is the most common unit for comparing energy sources or fuels, and it is also used in the pricing of natural gas. The SI unit for energy is the joule (J), and one BTU is approximately 1,055 J. The unit "therm" is used to represent 100,000 BTUs, while a decatherm is ten therms or one million BTUs. A quad, or quadrillion BTUs, is approximately one exajoule.
BTUs are also important when it comes to heating and cooling systems in homes. For example, a cooling unit typically needs about 20 BTUs for each square foot of living space that it's cooling. If a system is too big or too small for a home, it can result in higher energy costs and a subpar cooling experience.

BTU conversion factors
A British thermal unit (BTU) is a measure of the heat content of fuels or energy sources. One BTU is defined as the quantity of heat required to raise the temperature of one pound of liquid water by 1° Fahrenheit (approximately 39° Fahrenheit, the temperature at which water is at its greatest density). This amount of energy is approximately equal to that produced by burning a match.
BTUs are often used to rate the energy heat-producing capacity of appliances such as furnaces and to price heating fuels such as natural gas. They are also used to compare the average prices of different fuels over a given period.
To convert British thermal units to another unit of energy, such as joules, kilojoules, or megajoules, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without altering the value itself. For example, the BTU equivalent of fossil fuels consumed in the United States in 2023 was:
- Petroleum: 7.40 billion barrels = 35.43 quadrillion BTU
- Natural gas: 32.51 trillion cubic feet = 33.61 quadrillion BTU
- Coal: 425.92 million short tons = 8.17 quadrillion BTU
Note that these conversion factors are approximate and that the BTU content of fuels varies slightly from country to country.

BTU in diesel fuel
British Thermal Units (BTU) are a measure of the heat content of fuels or energy sources. One BTU is the quantity of heat required to raise the temperature of one pound of liquid water by 1° Fahrenheit (F) at the temperature that water has its greatest density (approximately 39° F). This is approximately equal to the energy released by burning a match.
BTU is often used to compare different energy sources or fuels. For example, the U.S. Energy Information Administration (EIA) converts physical amounts of energy sources (volume or weight) into BTU equivalents to facilitate comparisons. In 2023, the EIA reported that the United States consumed 35.43 quadrillion BTU of petroleum, 33.61 quadrillion BTU of natural gas, and 8.17 quadrillion BTU of coal.
When it comes to diesel fuel, the BTU content can vary depending on factors such as sulfur content and location. According to the U.S. Energy Information Administration, one gallon of diesel fuel or heating oil with a sulfur content of less than 15 parts per million contains approximately 137,381 BTU. If the sulfur content is higher, between 15 and 500 parts per million, the BTU content increases slightly to 138,500 BTU per gallon.
Comparing the BTU content of diesel fuel with other fuels can help in understanding the energy content and efficiency of different energy sources. For instance, gasoline typically has a lower BTU content than diesel, with one gallon of finished motor gasoline containing about 10% fuel ethanol by volume resulting in approximately 120,214 BTU.
Additionally, BTU values can be used to compare the energy efficiency of different heating sources. For example, by converting the consumption data of natural gas and heating oil into BTU, one can determine which heating method uses more energy over a given period.

BTU in red diesel fuel alternatives
Red diesel, also known as off-road diesel, is a type of diesel fuel that is intended for off-road use only. It is marked with a red dye to distinguish it from regular diesel fuel and to indicate that it is exempt from road taxes. While red diesel offers the same performance as regular diesel, it is often a more cost-effective option for off-road vehicles and equipment.
In terms of British Thermal Units (BTU), which is a measure of the heat content of fuels, 1 gallon of diesel fuel or heating oil with a sulfur content of less than 15 parts per million is approximately equal to 137,381 BTU.
Now, let's explore some alternatives to red diesel fuel and their BTU values:
Industrial Heating Oil (IHO)
IHO is a low-priced alternative to red diesel, designed for commercial heating applications. It has the same physical properties as diesel and is commonly used in boilers, dryers, and heaters. IHO cannot be used as fuel for road vehicles, off-road vehicles, or any machinery that is not intended for heating purposes. While IHO offers cost savings, its BTU value is slightly lower than diesel, at 137,381 BTU per gallon for diesel compared to 136,500 BTU per gallon for IHO with a sulfur content of 15 to 500 parts per million.
HVO Fuel
HVO fuel is a clean-burning alternative that can be used as a drop-in replacement for both red diesel and regular diesel. It has the advantage of reducing greenhouse gas emissions by up to 90% and offers a significantly longer shelf life of up to 10 years. HVO fuel is a synthetic diesel with no FAME or sulfur content, reducing the risk of contamination. While HVO fuel may have a slightly different BTU value due to its different chemical composition, it is a viable alternative for backup generators and other applications.
Regular Diesel Fuel
Regular diesel fuel, also known as white diesel, is the standard diesel fuel used for on-road vehicles. It is a yellowish-clear color and does not contain the red dye found in off-road diesel. Regular diesel fuel has a BTU value of approximately 137,381 BTU per gallon for diesel with a sulfur content of less than 15 parts per million. This option is suitable for those who require diesel for on-road use and are willing to pay the associated taxes.
