Ukuguqula amandla
Guqula amandla phakathi kwejoules, ama-calories, kWh, BTU nezinye izinto.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Ingabe kune-joules eningi ekudlaleni kwe-calorie?
I-calorie yokudla yi-kilocalorie, elingana ne-4,184 joules (4.184 kJ). Ngakho-ke, isidlo esincane se-200 Calorie sinomthamo we-837 kJ we-energy.
Ingabe kune-joules eyizinkulungwane ezingu-1000 ku-kilowatt-hour?
Ihora elilodwa le-kilowatt liyi-3.6 million joules (3.6 MJ), ngoba liyi-1,000 watts egcinwe isikhathi esingu-3,600 sezinhlamvu. Le yiyunithi elinganiselwa kuyo i-bill yakho ye-electricity.
Yini i-BTU?
Iyunithi ye-British Thermal yi-energy ephakamisa i-pond eyodwa yamanzi nge-1 °F, cishe ama-joules angama-1,055. Ivame ukutholakala ekufudumeza nasekubekezeleni i-air-conditioning.
Ingabe kune-calorie eningi ku-kilojoule?
I-kilojoule eyodwa ilingana ne-0.239 ye-calorie ye-food (kcal). Ngakho-ke, ukuthatha i-2,000 kcal ngosuku kuzoba ngu-8,368 kJ, isithombe esisetshenziswa kuma-European nutrition labels.
Yini ushintsho phakathi kwe-calorie ne-calorie?
A calorie encane (cal) 4.184 joules, ngenkathi ukudla Calorie nge capital C kuyinto kilocalorie - 1,000 ama-calorie amancane, noma 4,184 joules. Ukudla izihloko njalo isho eyodwa enkulu.
Ngiguqula kanjani i-kWh ibe yi-joules nge-energy converter?
Lo mguquli we-energy uphindaphindo lwe-kilowatt-hours nge-3,600,000 ukuze uthole ama-joules, ngoba i-kWh eyodwa i-1,000 watts ngemizuzu engu-3,600. Ngakho-ke i-2 kWh i-7.2 million joules.
