Model calculation · not experimental data
a = ln(RH/100) + 17.625 T/(243.04+T) Td = 243.04 a/(17.625−a)
MODEL & BOUNDARIES
Know what the result means.
Magnus approximation over liquid water, restricted here to 0–50°C. It is not a fog-formation forecast or an ice-saturation calculation. Absolute humidity uses the ideal-gas relation.
Version 1.0 · SI quantities are used internally, with displayed input units converted explicitly. Retain your assumptions with any exported result.
