Does anyone know of a decent non-proprietary function that converts dry-bulb temperature and relative humidity into a combination measure that, assuming constant light/wind/etc, is meaningful about subjective experience of atmospheric conditions? Heat index doesn't handle common indoor conditions.

Do you know about dew point?

There's a simple approximation for humidities above 50%: temp - (100-RH)/5

So if it's 23 C, and the RH is 70%, 23 - (100-70)/5 = 17 C. Not sure if the formula works in Fahrenheit.

Problem is that you have to memorize comfortable dew point ranges, they're not intuitive out of the box, but crudely, 10-16 C is good, 20-23 is like muggy Boston or Chicago, 25+ is tropical (including Tokyo in August.)

I'd heard about it but did not know it was usable this way, thanks!
