About watt-hours and joules
The Conversion Formula
To convert watt-hours to joules, multiply the value by the conversion factor: 1 Wh = 3600 J. For a worked example, suppose you need to convert 25 Wh to joules: 25 × 3600 = 90000 J. To convert in the opposite direction, divide by 3600, or equivalently multiply by 0.000277778.
About watt-hours
The watt-hour (Wh) is a smaller version of the kilowatt-hour. It is the standard for rating the capacity of batteries in laptops, smartphones, and power banks. Airlines often limit spare batteries to 100Wh for safety. watt-hours are commonly used in Laptop batteries, Power banks, Smartphone specs, and Drone batteries, Portable speakers.
A typical phone battery holds 10-15 Wh.
About joules
The Joule (J) is the standard unit of energy in the International System of Units (SI). It is named after James Prescott Joule, who proved that heat is a form of energy. One Joule is the work done by a force of one Newton moving an object one meter. It is a small unit: lifting a small apple one meter takes about 1 Joule. joules are commonly used in Scientific research, Physics education, Electronics ratings, and Kinetic energy calculations, Work done.
The energy of a heartbeat is roughly 1 Joule.
When Would You Convert watt-hours to joules?
Converting between watt-hours and joules is one of the most common energy conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 Wh = 3600 J) memorized or bookmarked can save time in professional and everyday contexts alike.
