convertimate Heat transfer

Watts per square meter-kelvin to kcal per hour-m²-°C

Type a value in W/(m²·K) to get it in kcal/(h·m²·°C) instantly.

21.5kcal/(h·m²·°C)

That's about the same as moving air. With 10 °C across it, that moves about 250 W per square meter.

What it means

How fast does heat leave?

Values depend strongly on flow speed, surface shape and whether the fluid changes phase.

The math

How to convert W/(m²·K) to kcal/(h·m²·°C)

To convert watts per square meter-kelvin to kcal per hour-m²-°C, multiply by 0.859845.

Example: 25 W/(m²·K) × 0.859845 = 21.4961 kcal/(h·m²·°C).

In the other direction, 1 kcal/(h·m²·°C) = 1.163 W/(m²·K).
