BTU per hour-ft²-°F to kcal per hour-m²-°C
Type a value in BTU/(h·ft²·°F) to get it in kcal/(h·m²·°C) instantly.
122.1kcal/(h·m²·°C)
That's 1.42× as effective as flowing oil, while flowing water is 3.5× higher. With 10 °C across it, that moves about 1,420 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 BTU/(h·ft²·°F) to kcal/(h·m²·°C)
To convert BTU per hour-ft²-°F to kcal per hour-m²-°C, multiply by 4.88243.
Example: 25 BTU/(h·ft²·°F) × 4.88243 = 122.061 kcal/(h·m²·°C).
In the other direction, 1 kcal/(h·m²·°C) = 0.204816 BTU/(h·ft²·°F).
