Note that rounding errors may occur, so always check the results. Our Watts to Joules converter also supports conversion from MilliWatts (mW), Watts (W), KiloWatts (KW), and MegaWatts (MW) to KiloJoules (kJ) and MegaJoules (mJ) per second, per minute or per hour. dom_i.query = jQuery.noConflict(true); This means that for every extra joule that is transferred per second, the power increases by one watt. var count = 1; : dom_i.query(this).attr("alt").trim(); She exerts a force of magnitude 22 N on the free end of the crank handle, and this end moves in a circular path of radius 0.28 M.

Example: It takes a particular kettle 1 minute and 46 seconds to boil a quantity of water. if(imgMarginRight.indexOf("px") > 0){ Using the fact that 1 calorie = 4.2 joules, and the appropriate time conversions show that this rate of energy usage is about the same as a 100 watt light bulb. } What was the power used, i.e. imgWidth = imgWidth.replace("px",""); if (imgTitle != '') { } Assuming no weight gain or loss, this also means that 2500 kilocalories are used by the body in a day. var imgMarginLeft = dom_i.query(this).css("margin-left") == undefined ?

"); But people can also have power that is measured in watts much like a light bulb or refrigerator. Example Two electric motors are used to lift a 2 N weight through a vertical height of 10 m. Converting kilocalories into watts has the advantage of allowing yourself to determine how much power you are getting from your diet. 1 calorie = 4.2 joules 2500 kilocalories = 1.05 × 10 7 J 1 day = 86400 s P = W/t = 1.05 × 10 7 J/86400 s = 121.5 W.

You abbreviate a watt as simply W, so a 100-watt light bulb converts 100 joules of electrical energy into light and heat every second.
