Malunga nale Calculator

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 ebuza rhoqo

Ingaba kukho i-joules ezili-100 kwi-calori yesondlo?

I-calori yesondlo yi-kilocalorie, elingana ne-4,184 joules (4.184 kJ). Ngoko ke isidlo esincinci esinomlinganiselo we-200 Calorie sinomlinganiselo we-837 kJ woxinzelelo.

Ngaphi i-joules kwikilowatt-iyure?

Iyure enye yekilowatt yi-3.6 yezigidi zee-joules (3.6 MJ), kuba yi-1,000 ye-watts egcinwe kwimizuzu engama-3,600. Yiyunithi esetyenziselwa ukulinganisa ityala lakho le-elektroniki.

Yintoni i-BTU?

Iyunithi yeBrithani ye-Thermal yi-energy yokunyusa i-pund enye yamanzi nge-1 °F, malunga ne-1,055 joules. Iqhelekileyo kwi-heating kunye ne-air-conditioning ratings.

Ii-calories eziphi kwi-kilojoule?

I-kilojoule enye imalunga ne-0.239 ye-calorie yesondlo (kcal). Ngoko ke, ukutya okune-2,000 kcal ngosuku kumalunga ne-8,368 kJ, ixabiso elisetyenziswa kwi-labels yokutya kwe-European.

Yintoni utshintsho phakathi kwe-calorie kunye ne-calorie?

I-calori encinci (cal) yi-4.184 joules, ngelixa i-calori yokutya enesivakalisi C yi-kilocalorie — 1,000 ye-calori encinci, okanye i-4,184 joules. Iilabels zokutya zisoloko zithetha enye enkulu.

Ndiyiguqula njani i-kWh ibe yi-joules ngesixhobo sokuguqula amandla?

Le nto iguqula amandla iphindaphindo iiyure zekilowatt nge-3,600,000 ukuze ifumane ii-joules, kuba i-kWh enye yi-1,000 ye-watts ngemizuzu engama-3,600. Ngoko ke i-2 kWh yi-7.2 yezigidi zee-joules.
