Various forms of energy can be measured in joules, such as kinetic energy, potential energy, heat energy, and electrical energy. Joules are a unit of measurement for energy and can be used to quantify the amount of energy present in a system or the amount of work done.

The unit of measurement for electromagnetic energy is the joule (J).
Power is measured in watts when work is measured in joules and time is measured in seconds.
Watts are measured by Joules divided by seconds. The watt is the unit of power, representing the rate at which energy is transferred. It is calculated by dividing the energy (measured in Joules) by the time (measured in seconds) over which the energy is transferred.
Thermal energy is typically measured in units of joules (J) or kilojoules (kJ). It can also be measured in calories (cal) or British thermal units (BTU) depending on the context.
