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.
