Full API documentation

Explanation

Formula: Joules per kilogram-kelvin = Calories per gram-degree Celsius × 4,186.8. Why: the route normalizes to joules per kilogram-kelvin, then applies the fixed calorie-to-joule relationship together with the gram and Celsius interval basis used by chemistry-style units.

Calories per gram-degree Celsius (cal/(g·°C)): a legacy chemistry and food-science heat-capacity unit based on calories, grams, and Celsius intervals.

Joules per kilogram-kelvin (J/(kg·K)): the standard SI-style specific heat capacity unit expressing how many joules are needed to raise one kilogram by one kelvin.

This route is useful when translating between SI heat-capacity data and calorie-based chemistry or food-science references without changing the underlying material property.

This conversion is purely multiplicative because both units reduce through one joules-per-kilogram-kelvin basis, and temperature intervals are handled as fixed scale relationships with no offset term.

Method & Reference
