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.
Zvimwe zvinobvunzwa zvakanyanya
Mazuva mangani ari muzuva?
A chikafu Calorie ndiro kilocalorie, iyo inoenzana 4,184 joules (4.184 kJ). So 200 Calorie snack inotora pamusoro 837 kJ simba.
Mazuva mangani ari mukirowatt-hour?
Chimwe kilowatt-hour ndiro 3.6 miriyoni joules (3.6 MJ), nokuti ndiro 1,000 watts yakachengetwa kwe3,600 masekondi.Ini ndiro chikwata yako magetsi bhiri inoongororwa mu.
Chii chinonzi BTU?
British Thermal Unit (BTU) isimba rinodiwa kuti ridzivise 1 pound yemvura ne1 °F, kana kuti 1,055 joules.Inoshandiswa zvakanyanya mukushandisa kwemagetsi uye kupisa.
Ma calories mangani ari mu kilojoule?
Chimwe kilojoule chine 0.239 calorie (kcal) saka 2,000 kcal yezuva nezuva inoita 8,368 kJ, iyo inonzi inoshandiswa muEurope pakudhinda zvinhu zvinovaka muviri.
Chii chinonzi chiyero chekuziva kuti munhu ane ma calories mazhinji here?
A chidiki calorie (cal) ndiro 4.184 joules, apo kudya Calorie nemari C ndiro kilocalorie — 1,000 chidiki calories, kana 4.184 joules. Nutrition mapepa anorevawo nguva dzose zhinji.
Maitiro ekushandura kWh kuenda kujoule nekushandisa iyi energy converter?
Iyi simba converter anowedzera kilowatt-hours ne 3,600,000 kuti uwane joules, nekuti imwe kWh 1,000 watts 3,600 masekondi. So 2 kWh 7.2 miriyoni joules.
