When does moisture condense
I was wondering if there was a website or mathematical forumula to determine when moisture in the air will condense. For example, it the interior temperature is 70F and humidity is 40% then the moisture in the air will condense once the window's temperture falls below "X" F.

This is also a good site:

To answer your example of 70 degrees/40% relative humidity, the window surface will begin condensing moisture once its interior surfaces fall below 44 degrees.

And it varies infinitely, depending on the exact temperature. That's why we measure the humidity as a RELATIVE number. When it gets to 100%, we change the name to water.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

Consult a psychometric chart.
