Joule, being a measure of energy, can accumulate over time. For example, a battery can store a certain number of joules. Watt illustrates how quickly the stored joules in that battery can be used or drained. 16 Understanding the difference between joule and watt is crucial in various applicat...
meter (m) and second (s), all of which are constructed from the standard's defining constants. The watt is a measure of the rate of energy transfer over a unit of time, with one watt equal to one joule

A watt (W) is a unit of power, and power is the rate at which energy is produced or consumed. Think of watts as a measure of electrical flow. Does an electrical device need a big flow or a small flow to work? For example, a 100 W light bulb uses energy at a higher rate than...
Note: Watthours (also spelled Watt-hours) is a measure of energy and Watts is a unit of power. (Power multiplied by time is enery). Enter the Watt-hours Wh and hours below and then click on the "Calculate Watts" button: Wh: Hours: W The formula is (Wh)/(h) = (W). For ...
A unit used to measure power, equal to one joule of work per second. In electricity, a watt is equal to the amount of current (in amperes) multiplied by the amount of potential (in volts). The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton...
What Is a Watt-Hour? The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period. Watt-hours are usually abbreviated as Wh, although the formally adopted expression is W·h. The abbreviation W h is also sometimes used. For example, 1 watt-hour...
Watts and kilowatts (one thousand watts) aremeasures of electricity volume: how much electricity it takes to power something. For customers, kWh will be the most familiar. This is how your energy is measured as it passes your meter. It’s a measure ofenergy use over a length of time. ...
