What is the unit of measure for work in the SI system?

In the SI system, work is measured in Joules. A Joule is defined as the amount of work done when a force of one newton is applied over a distance of one meter. This unit is derived from the basic units of the metric system and effectively quantifies energy transfer or work performed.

Using Joules as a standard unit allows for easy calculations and conversions within the context of physics and engineering, particularly in scenarios involving mechanical systems, electrical systems, and thermodynamics. While other units, such as foot-pounds, may be utilized in different measurement systems, they do not conform to the SI system's standard. Thus, Joules remain the accepted unit for work in this context.
