Which quantity is measured in joules?

Joules measure energy. The joule is the unit used for energy—it's the amount of energy required to do work or the amount of energy a system has. Work itself is force times distance, and energy can take forms like kinetic or potential energy, all expressed in joules. The other quantities use different units: distance in meters, speed in meters per second, and time in seconds. So energy is the quantity measured in joules.
