Joules vs. Watthours

What's the Difference?

Joules and Watthours are both units of energy measurement, but they differ in their applications and scales. Joules (J) are the standard unit of energy in the International System of Units (SI) and are used to measure energy in various fields, including physics, chemistry, and engineering. On the other hand, Watthours (Wh) are commonly used in the context of electrical energy consumption. One Watthour is equal to the energy consumed by a one-watt device operating for one hour. While Joules are a more general unit applicable to all forms of energy, Watthours are specific to electrical energy consumption and are commonly used in utility bills and energy monitoring devices.
