Relative Humidity, Dew Point, Temperature Calculator

This tool calculates Relative Humidity, Dew Point, and Temperature based on two inputs.

Output values are rounded to the second decimal place.

Equations

August-Roche-Magnus Estimation

RH(Relative Humidity) = 100*(exp((17.625*TD)/(243.04+TD))/exp((17.625*T)/(243.04+T)))

TD(Dew Point) = 243.04*(ln(RH/100)+((17.625*T)/(243.04+T)))/(17.625-ln(RH/100)-((17.625*T)/(243.04+T)))

T(Temperature) = 243.04*(((17.625*TD)/(243.04+TD))-ln(RH/100))/(17.625+ln(RH/100)-((17.625*TD)/(243.04+TD)))
