Kcal to ws Conversion Formula:
One Kilocalories is equal to 4184 Watt-second.
Formula: 1 kcal = 4184 Ws
By using this conversion factor, you can easily convert any energy from kilocalories to watt-second with precision.
How to Convert kcal to Ws?
Converting from kcal to Ws is a straightforward process. Follow these steps to ensure accurate conversions from kilocalories to watt-second:
- Select the Kilocalories Value: Start by determining the kilocalories (kcal) value you want to convert into watt-second (Ws). This is your starting point.
- Multiply by the Conversion Factor: To convert kilocalories to watt-second, multiply the selected kcal value by 4184. This factor is essential for accurately converting from a larger unit (kcal) to a much smaller unit (Ws).
- Illustration of Multiplication:
- 1 kcal = 4184 Ws
- 10 kcal = 41840 Ws
- 100 kcal = 418400 Ws
- Find the Conversion Result: The result of this multiplication is your converted value in watt-second unit. This represents the same energy but in a different unit.
- Save Your Watt-second Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in watt-seconds.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the kilocalories value by 0.000239005736137667. This alternative method also gives you the correct energy in watt-seconds.
- Illustration of Division:
- Ws = kcal ÷ 0.000239005736137667

Kilocalories to Watt-second Examples
Example 1:
Convert 0.8 Kilocalories to Watt-second.
Solution:
We know that one Kilocalories is equivalent to 4184 Watt-second.
Therefore,
0.8 kcal = 0.8 x 4184 Ws.
0.8 kcal = 3347.2 Ws.
Hence, 0.8 Kilocalories is approximately equal to 3347.2 Watt-second.
Example 2:
Convert 9 Kilocalories to Watt-second.
Solution:
We know that one Kilocalories is equivalent to 4184 Watt-second.
Therefore,
9 kcal = 9 x 4184 Ws.
9 kcal = 37656 Ws.
Hence, 9 Kilocalories is approximately equal to 37656 Watt-second.
Example 3:
Convert 58 Kilocalories to Watt-second.
Solution:
We know that one Kilocalories is equivalent to 4184 Watt-second.
