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.

Chii formula inoshandiswa kune mabwe point?
Magnus-Tetens approximation neAlduchov-Eskridge constants: γ = ln(RH/100) + 17.625·T/(243.04+T), uye dew point = 243.04·γ/(17.625−γ), ne T mu °C. Ichokwadi mukati memakore mashoma emakore
Nei dew point chinhu kupfuura humidity?
Relative humidity inoenderana nemamiriro ekunze, saka 90% humidity pa10 ° C inonzwa yakachena, asi 60% pa30 ° C inonzwa yakaoma. Dew point ndiyo yakazara metric yehumidity, saka inotevera sei sticky iyo air inonzwa zvakanyanya zvakanaka.
Chii chipo chemvura chinonzwa kugadzikana?
Pamusoro pe13 °C (55 °F) zvinonzwa zvakasununguka uye zvakaoma, 16-18 °C (60-65 °F) zvinotanga kugara zvakaoma, uye pamusoro pe21 °C (70 °F) zvinonetsa uye zvinonetsa kutonhora.

Hapana. Pakutanga, hum point inoenderana nemhepo tembiricha, iyo inoitika pa100% humidity uye kana iyo nzvimbo yakazara yaiswa nemvura. Kana kupisa kwakanyanya uye mvura ichibuda, hum point inoramba iri pasi peiyo tembiricha yazvino.
Sei dew point inoenderana nemvura yemvura uye nemvura yekuumbwa?
Kana zvinhu kana mhepo ichitonhora kusvika panzvimbo yemvura, mvura inobuda mumvura. Izvi zvinoreva kuti kana mvura ichibuda mumvura, mvura inobuda muvhu, uye mvura inobuda muvhu inobuda mumvura. Kana mvura ichibuda muvhu, mvura inobuda muvhu inobuda muvhu.
Chiratidzo chekuora chinogona kuchinja kana tembiricha ichichinja?
Hapana pamwechete - the dew point inoratidzwa chokwadi moisture zvinhu, izvo zvinogara kuiswa semhepo inotonhora kana kutonhora. Chii chinochinja ne tembiricha ndeye humidity, izvo ndizvo nei dew point iri stable measure of muggy air.
Maitiro akajeka sei Magnus-Tetens formula iyi inoshandisa?
With the Alduchov-Eskridge coefficients it is accurate to within a few tenths of a degree Celsius across the normal range of weather temperatures and humidities, which is well within the precision of everyday humidity readings.
