Can I enter wet-bulb?

Not in this phase — use dry-bulb and RH, or pair with other tools that supply RH.

Is moist-air density used here?

No. W and h use the standard approximate formulas; density-based flows are separate.

Psychrometric Calculator

Uses the same Magnus-type saturation pressure as the dew point tool, then humidity ratio W = 0.621945·P_w/(P−P_w) and h = 1.006·T + W·(2501 + 1.86·T) per kg dry air. Fixed total pressure; no wet-bulb or mixing sections.

Como usar

1Enter dry-bulb °C and RH (0–100%, exclusive 0).
2Set barometric pressure (default sea-level) within the allowed band.
3Review dew point, W, and approximate enthalpy.
