About Watt-hour (Wh)
One watt sustained for one hour equals 3,600 joules. The watt-hour is used for small-scale electrical energy measurements such as battery capacity in consumer electronics. A smartphone battery typically holds 10-20 Wh, and laptop batteries range from 40 to 100 Wh.
About Joule (J)
The SI derived unit of energy, one joule equals the work done by a force of one newton moving an object one meter. Named after James Prescott Joule, who demonstrated the mechanical equivalent of heat, the joule is used in physics, chemistry, and engineering for all forms of energy, work, and heat.
