Temp (deg C) to Watts
by Philip Rougier on 09/24/02 at 15:10:46
Can you please tell me where the Celsius heat unit to Watt hour conversion comes from (in the online conversion), ie the formula ? It looks a bit like the Stephan-Bolztmann constant, but that's only part of the S-B formula, which has a T^4 in it.
What I'm trying to do is calculate the effective energy in Watts emitted from a window by taking external glass temp and internal air temp, in deg C

Well there isn't a formula really, just a conversion factor.
1 centigrade heat unit (International Table) = 0.52752793 watthour
If you are looking for a formula for converting it using non-standard temperature and pressure, I wont be able to help you there. But I do have conversion factors for several different temperatures, if that will help.
