How to Convert Kilocalorie/Kilogram-°C to Joule/Kilogram-Kelvin

To convert from Kilocalorie/Kilogram-°C (kcal/(kg·°C)) to Joule/Kilogram-Kelvin (J/(kg·K)), multiply the value by 4,184.

Formula: J/(kg·K) = kcal/(kg·°C) × 4,184

Reverse: kcal/(kg·°C) = J/(kg·K) × 0.0002390057

Step-by-Step Example

Start with your value in Kilocalorie/Kilogram-°C. For example: 5 kcal/(kg·°C)
Multiply by the conversion factor: 5 x 4,184
The result is: 20,920 J/(kg·K)
