BTU to Joules Converter

Convert thermal energy in British Thermal Units (BTU) to physical work in joules (J).

How BTU to Joules works

A British Thermal Unit (BTU) is a thermal unit of energy. It is defined as the amount of heat required to raise the temperature of one pound of liquid water by one degree Fahrenheit.

In physics and engineering, the standard International Table (IT) conversion rate defines 1 BTU as approximately 1,055.05585 joules. To convert BTUs to joules, multiply the BTU value by 1,055.056.

Formula

1J = BTU × 1,055.056

Based on the international steam table BTU value.
