The SI unit of heat is the Joule (J).
Heat, like all forms of energy, is measured in Joules according to the International System of Units.
Why Joules?
The reason heat is measured in Joules is because heat is a form of energy transfer. The reference states, "As all the energy is represented in Joules (J), therefore, heat is also represented in Joules." This means that whether you're talking about kinetic energy, potential energy, or heat energy, the fundamental unit is the Joule.
Understanding Joules
- A Joule can be defined as the amount of energy needed to do one Newton of work over a distance of one meter.
- Another way to think of it: it's the energy required to raise the temperature of a specific mass by one degree, according to the reference.

Practical Insights
It is essential to use Joules for consistency in scientific calculations and measurements, ensuring that all energy-related quantities are expressed using the same fundamental unit.
