This question is NOT related to sundials so I apologise in advance. I have made a wet and dry bulb hygrometer to measure realtive air humidity. Unfortunately the only table to convert temperature differences into relative humidity is in one of my children's books. Perhaps some diallist would know where I could find a more advanced one on the 'net.
