An energy converter changes a quantity of energy between joules and kilojoules, calories and kilocalories (the food Calorie), watt-hours and kilowatt-hours, the BTU, the foot-pound and the electronvolt. Every value passes through the joule as a common base.
The conversions people reach for most are 1 food Calorie (kcal) = 4,184 joules, 1 kilowatt-hour = 3,600,000 joules and 1 BTU ≈ 1,055 joules. Because a food Calorie is really a kilocalorie, a "200 Calorie" label means 200 kcal, or about 837 kJ.
Worked example: to convert 200 kilocalories to kilojoules, multiply by 4.184, giving about 837 kJ. To convert 1 kWh to megajoules, note it is 1,000 W sustained for 3,600 s, so 3.6 MJ. A results table shows the same energy in every unit at once, useful for nutrition labels, utility bills and physics homework.

Kodi pali ma joules angati m'mapulogalamu a chakudya?
A chakudya Calorie ndi kilocalorie, yomwe ndi yofanana 4,184 joules (4.184 kJ).Kotero 200 Calorie snack ali pafupifupi 837 kJ ya mphamvu.
Kodi pali ma joules angati m'kilowatt-hour?
M'malo mwake, kilowatt-hour imodzi ndi 3.6 miliyoni joules (3.6 MJ), chifukwa ndi 1,000 watts yokhala ndi 3,600 masekondi. Ndi yunitsi yomwe imawerengedwa mu ndalama zanu zamagetsi.
Kodi ndi BTU?
British Thermal Unit ndi mphamvu yowonjezera imodzi pa 1 pound ya madzi ndi 1 ° F, pafupifupi 1,055 joules.Izi ndi zofala mu kutenthetsa ndi mpweya-kukonzekera mfundo.
Kodi pali ma calories angati mu kilojoule?
Mmodzi kilojoule ndi zoposa 0.239 chakudya Calories (kcal).The 2,000 kcal tsiku logwiritsa ntchito ndi pafupifupi 8,368 kJ, chiwonetsero chogwiritsa ntchito pa European nutrition labels.
Kodi pali kusiyana kotani pakati pa calorie ndi Calorie?
A ochepa calorie (cal) ndi 4.184 joules, pamene chakudya Calorie ndi kapitali C ndi kilocalorie — 1,000 ochepa calorie, kapena 4,184 joules. Nutrition masamba nthawi zonse kumatanthauza lalikulu.
Kodi ndingasinthe kWh kuti joules ndi magetsi Converter?
This energy converter multiplies kilowatt-hours by 3,600,000 to get joules, because one kWh is 1,000 watts for 3,600 seconds. So 2 kWh is 7.2 million joules.
