## Description

Psychrometer °F is a Chrome extension that computes thermal comfort and essential air properties from simple dial inputs. Choose among three psychrometric types (Assmann, Natural, Sling), view color-coded temperatures, and assess whether conditions are in the comfortable range. 

Enter values as temperature and humidity, dew point, or wet-bulb to derive dry-bulb temperature, dew point, relative humidity, vapor pressures, enthalpy, specific volume, and more. The app can auto-fetch outdoor weather data (with location permission), supports a wide input range, and includes notes on accuracy and limitations.
