Frequently Asked Questions
How do I convert kilocalories to joules?
Multiply kilocalories by 4,184. For example, 1 kcal = 4,184 joules. This is commonly used in nutrition calculations.
What's the difference between calories and kilocalories?
1 kilocalorie (kcal) = 1,000 calories (cal). Food 'Calories' (with capital C) are actually kilocalories. So when you see 100 Calories on a food label, that's 100 kcal or 100,000 cal.
How many kWh in a BTU?
1 kWh = 3,412 BTU. To convert BTU to kWh, divide by 3,412. This is useful for comparing heating/cooling efficiency with electrical energy.
What is a joule?
A joule (J) is the SI unit of energy. It's defined as the energy transferred when a force of 1 newton moves an object 1 meter. 1 kWh = 3.6 million joules.
How do I convert food calories to kWh?
1 food Calorie (kcal) = 0.001163 kWh. So 1,000 kcal = 1.163 kWh. This shows the energy content of food in electrical terms.
