The dew point is the temperature to which air must be cooled for its water vapour to start condensing into dew, and it is the most honest single measure of how much moisture the air actually holds. A higher dew point means more water in the air and a muggier, stickier feel; it is also the temperature at which fog forms, grass gets damp overnight and a cold drink beads with condensation. This dew point calculator derives it from the air temperature and the relative humidity you enter.
It uses the Magnus-Tetens approximation with the Alduchov-Eskridge coefficients (a = 17.625, b = 243.04 °C): first γ = ln(RH / 100) + aT / (b + T), then the dew point = bγ / (a − γ), with T in °C. As a worked example, air at 25 °C and 60% relative humidity has a dew point of about 16.7 °C — comfortable edging toward sticky. Drop the humidity to 30% at the same 25 °C and the dew point falls to roughly 6 °C, distinctly dry. The method is accurate to within a few tenths of a degree across ordinary weather, and the tool works in either °C or °F.
Dew point predicts comfort far better than relative humidity, because relative humidity depends on temperature: 90% humidity on a cold morning feels dry, while 60% on a hot afternoon feels oppressive. As an absolute measure, dew point cuts through that — below about 13 °C (55 °F) feels comfortable, 16–18 °C (60–65 °F) starts to feel sticky, and above 21 °C (70 °F) is oppressive and hard to cool down in. The same value tells you when condensation will form on windows, pipes and aircraft surfaces.

The Magnus-Tetens approximation with Alduchov-Eskridge constants: γ = ln(RH/100) + 17.625·T/(243.04+T), and dew point = 243.04·γ/(17.625−γ), with T in °C. It is accurate to within a few tenths of a degree over normal weather conditions.
