Unit Definitions

What is a Megajoule (MJ)?

Metric (SI)Worldwide

A Megajoule (MJ) is a unit of energy in the International System of Units (SI), equivalent to one million joules.

History

The joule was named after the English physicist James Prescott Joule, who studied the nature of heat and energy. The megajoule, as a larger unit, was adopted to simplify calculations in engineering and energy sectors.

Current Use

MJ is commonly used in scientific contexts, electricity generation, and by industries requiring large-scale energy measurements.

What is a BTU (BTU)?

ImperialUnited States

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

History

The BTU has been in use since the early days of the steam engine and has its roots in the heating and cooling industries. It remains a standard measure for energy in the United States.

Current Use

BTUs are widely used in heating, cooling systems, and energy sectors, particularly in the U.S., where appliances and fuels are often rated by their BTU output.
