Is there a humidity calculator out there?
I live in a leaky house, the inside humidity tracks the outdoor humidity with a lag and temperature adjusted, but i want to be able to input an outdoor temp and humidity and calculate what the indoor humidity will eventually become at 20ºC (theoretically of course).
Basically i want to know what the resulting humidity would be at an input temp and humidity if that air was raised to 20C
I know the outdoor will eventually change before the indoor catches up but it would be useful to me.

Adjust your temp and humidity, keeping the dewpoint constant, and you have your answer.
Further discussion of your question and how to answer it can be found here: How to Use the Psychrometric Chart.
That one does the job....but for just RH and dew pts a simplier one to use
Temperature, Dewpoint, and Relative Humidity Calculator = http : // einstein.atmos.colostate . edu/~mcnoldy/Humidity.html
Enter temp and then enter either dew pt or RH to find the other.
