About the units
Calorie per gram °C (cal/(g⋅°C))
The calorie per gram °C (cal/(g⋅°C)) is a unit of specific heat capacity. One calorie per gram °C equals 4,184 joules per kilogram kelvin (J/(kg⋅K)).
Joule per kilogram kelvin (J/(kg⋅K))
The joule per kilogram kelvin (J/(kg⋅K)) is a unit of specific heat capacity in the International System of Units (SI).
Frequently asked questions
How many joules per kilogram kelvin are in one calorie per gram °C?
There are 4,184 joules per kilogram kelvin in one calorie per gram °C, and this value is exact by definition.
How do I convert calories per gram °C to joules per kilogram kelvin?
Multiply the number of calories per gram °C by 4,184. For example, 10 cal/(g⋅°C) × 4,184 = 41,840 J/(kg⋅K).
How many calories per gram °C are in one joule per kilogram kelvin?
One joule per kilogram kelvin equals 0.0002390057361 calories per gram °C. That is the reverse factor, 1 ÷ 4,184.
What is 10 calories per gram °C in joules per kilogram kelvin?
10 cal/(g⋅°C) = 41,840 J/(kg⋅K).
Is this cal/(g⋅°C) to J/(kg⋅K) converter accurate?
