What is a megajoule (MJ)?

A megajoule is an SI derived unit of energy equal to one million joules, used to measure transferred or stored energy such as heat, work, chemical, or electrical energy.

What does Btu (IT) stand for and where is it used?

Btu (IT) stands for British thermal unit as defined by the International Steam Tables and is commonly used in thermodynamic and engineering contexts to quantify heat amounts.

Can I use this tool for converting power ratings?

No, this tool is designed specifically for energy quantity conversions and should not be used for converting power or rate measurements.
