To convert from Kilocalorie (kcal) to Watt-minute (Wm), use the following formula:
With is the ratio between the base units Joule (J) and calorie (cal).
Let's convert 5 Kilocalorie (kcal) to Watt-minute (Wm).
Using the formula:
Therefore, 5 Kilocalorie (kcal) is equal to Watt-minute (Wm).

A kilocalorie (kcal) is a unit used to measure energy.
Just as a kilometer is 1,000 meters, one kilocalorie is equal to 1,000 small calories (cal).
It's the most common unit for discussing the energy content of food.
Have you ever noticed the word "Calories" on a food label? What you're actually seeing is a kilocalorie (kcal).
Here's the simple breakdown:
Essentially, in the world of nutrition, the terms Calorie and kilocalorie are used interchangeably.
The "small calorie" (cal) is a much smaller unit and is primarily used in science labs.
Scientifically, a kilocalorie is the amount of energy needed to heat one kilogram of water by one degree Celsius.
This precise measurement allows scientists to determine how much energy your body can get from the macronutrients in your food, such as:
When a food label says a serving has 100 Calories, it means that's the amount of energy your body can use from it.
The kilocalorie isn't just for food!
As a fundamental unit of energy, it's also used in fields like physics and chemistry to measure energy in chemical reactions and heat transfer.
A Watt-minute (Wm) is a unit of energy that measures the total energy consumed when one watt of power is applied for exactly one minute.
The plural form is Watt-minutes.
To make it easier to understand, think of it like filling a bucket with a hose. If a watt is the speed at which water flows, a Watt-minute is the total amount of water in the bucket after the hose has been running for one minute.
One Watt-minute is precisely equal to 60 Joules (J).
This conversion is simple because a watt is defined as one joule per second (1 W = 1 J/s). Since there are 60 seconds in a minute, the calculation is straightforward:
1 Watt-minute = 1 Watt × 60 seconds = 60 Joules
This simple formula makes the Wm to J conversion easy to remember for any energy calculation.
While you're more likely to see Watt-hours (Wh) or kilowatt-hours (kWh) on your electricity bill, the Watt-minute is an essential unit for more precise energy measurement in specific fields.
It's most useful in situations where energy is tracked over short intervals, such as:
