How to transform Joules come Watt-hours

To convert a joule measurement come a watt-hour measurement, division the energy by the conversion ratio.

because one watt-hour is same to 3,600 joules, you can use this an easy formula to convert:

Joules

The joule is the power equal come the pressure on things of one newton at a street of one meter.<1> One joule is equal to the heat energy dissipated through the present of one ampere v one ohm of resistance because that one second.

One joule is likewise equal to the energy needed to relocate an electrical charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal come the one watt-second.

The joule is the SI derived unit for power in the metric system. Joules deserve to be abbreviated together J; for example, 1 joule can be created as 1 J.

Watt-hours

The watt-hour is a measure up of electrical energy equal to one watt of power over a one hour period.

Watt-hours space usually abbreviated together Wh, although the formally embraced expression is W·h. The abbreviation Wh is additionally sometimes used. Because that example, 1 watt-hour deserve to be written as 1 Wh, 1 W·h, or 1 Wh.

In formal expressions, the focused dot (·) or an are is offered to separate units offered to show multiplication in one expression and to protect against conflicting prefixes being misinterpreted together a unit symbol.<2>
