Unit relationship
Formula
cal = J ÷ 4.184 ; kWh = J ÷ 3600000= 23900.573613767
Note
This result is a simplified model: it converts the single value you entered with the exact factors shown, and rounds to the display precision. It does not know your measurement's accuracy, and cooking or density conversions depend on how an ingredient is packed. Check critical figures against the original units.

How many joules are in a calorie?+
One (small) calorie equals exactly 4.184 joules, based on the thermochemical definition. The calculator uses this precise conversion, so results won't drift when converting back and forth repeatedly.
Is a food 'Calorie' the same as the calorie in this calculator?+
No — the Calorie on nutrition labels (capital C) is actually a kilocalorie, equal to 1,000 small calories, or 4,184 joules. This is one of the most common sources of confusion in energy conversions, so check whether you mean dietary Calories or scientific calories before entering a value.
What is a kWh and why would I convert joules to it?+
A kilowatt-hour is a unit of energy equal to 3,600,000 joules (3.6 megajoules), commonly used for electricity billing. Converting joules to kWh is useful when comparing a physics-based energy value (like heat output) to what you'd see on a utility bill.
Why does converting a large joule value to kWh give such a small number?+
Because a kWh represents a very large amount of energy (3.6 million joules), everyday physical quantities in joules — like the energy in a falling object — convert to tiny fractions of a kWh, while household electricity use over a day easily reaches several kWh.
How does this relate to converting energy to power?+
Joules measure energy (a total amount), while watts measure power (energy per second) — this calculator converts between energy units only. To get power, you'd need to also know the time period over which that energy was used or produced.
