Megajoules (MJ)

Definition

A megajoule (MJ) is a unit of energy equal to 1,000,000 joules (10⁶ J). It is used to express large-scale energy quantities.

History

The megajoule became commonly used with the growth of industrial energy measurement in the 20th century, particularly for fuel energy content and large engineering systems.

Current use

Megajoules are used to express the energy content of fuels (e.g., natural gas, gasoline), industrial process energy, and large-scale thermal systems in engineering and environmental science.

British Thermal Units (BTU)

Definition

A British Thermal Unit (BTU) is an imperial unit of energy defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It equals approximately 1,055.06 joules.

History

The BTU originated in the British imperial measurement system in the 19th century. Despite the global shift toward metric units, it remains entrenched in US, UK, and Canadian HVAC and energy industries.

Current use

BTUs are the standard unit for rating heating and cooling equipment (furnaces, air conditioners), measuring natural gas energy content, and comparing fuel efficiencies in North America.
