Frequently Asked Questions
-
What does calorie (th)/second/cm/°C measure?
-
It measures thermal conductivity as heat flow in thermochemical calories per second through a 1 cm thickness and 1 cm² area for a 1 °C temperature difference.
-
Why convert to watt/meter/K [W/(m*K)]?
-
Watt per meter per kelvin is the SI unit for thermal conductivity, widely used in modern engineering and scientific calculations.
-
Are there different types of calories affecting conversion?
-
Yes, confirming thermochemical versus international calorie definitions is important to ensure accurate conversions.
