Kuhusu kifaa hiki cha kupigia hesabu

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.

Maswali yaliyoulizwa mara nyingi

Ni nyumbu wangapi walio katika mkahawa wa Calorie?

A food Calorie is a kilocalorie, which equals 4,184 joules (4.184 kJ). So a 200 Calorie snack holds about 837 kJ of energy.

Ni punda wangapi wanaovalia saa ya kilowatt?

Saa moja ya kilowatt ni joli milioni 3.6 (3.6 MJ), kwa sababu ni wati 1,000 wanaotegemezwa kwa sekunde 3,600.

BHU ni nini?

A British Thermal Unit is the energy to raise one pound of water by 1 °F, about 1,055 joules. It is common in heating and air-conditioning ratings.

Ni kalori ngapi zilizo katika kilojoule?

One kilojoule is about 0.239 food Calories (kcal). So a 2,000 kcal daily intake is roughly 8,368 kJ, the figure used on European nutrition labels.

Kuna tofauti gani kati ya kalori na Kalori?

Kalori ndogo (kali) ni joli 4.184, huku chakula Calorie chenye C kuu ni kilocalrie KUTILI kalori ndogo 1,000, au 4,184 joli.

Ninabadilije kWh kuwa vibadili - sauti vya umeme huku nikiwa na mbadili - nishati hii?

Mbadili - nishati huyu aongeza kilowatt-saa kwa watu 3,600,000 ili kupata vifurushi, kwa sababu kWh moja ni wati 1,000 kwa sekunde 3,600. Kwa hiyo, kWh 2 kWh ni joli milioni 7.2.
