joule [J]

The SI-derived unit for energy, work, and heat, named after British physicist James Prescott Joule. 1 joule = 1 newton-meter = 1 watt-second. Widely used in physics, engineering, and nutrition (e.g., food energy is often labeled in kilojoules, kJ). Universally adopted and part of China’s statutory measurement system.
