What standard units makes up BTU?
British thermal unit (BTU), a measure of the quantity of heat, defined since 1956 as approximately equal to 1,055 joules, or 252 gram calories. It was defined formerly as the amount of heat required to raise the temperature of one pound of water 1° F.
How many BTUs are in a gallon of kerosene?
131,890 BTUs
Kerosene has 131,890 BTUs per gallon. 1.05 gallons equals the heat content of one gallon of oil.
Which fuel has the highest BTU output by volume?

What wood burns longest?
Hardwoods such as maple, oak, ash, birch, and most fruit trees are the best burning woods that will give you a hotter and longer burn time. These woods have the least pitch and sap and are generally cleaner to handle.

What makes a cord of wood a BTU?
A cord of wood is a volume unit and does not take wood density or moisture content into account. Wood heat content varies significantly with moisture content. The Btu conversion factors above are approximations. There are tables with heat contents for fuels and electricity in the appendices of the Monthly Energy Review.
Which is an example of a BTU Conversion?

What does a British thermal unit ( BTU ) mean?
A British thermal unit (Btu) is a measure of the heat content of fuels or energy sources. It is the quantity of heat required to raise the temperature of one pound of liquid water by 1 degree Fahrenheit at the temperature that water has its greatest density (approximately 39 degrees Fahrenheit).
