The following tables calculate Dew Point and Relative Humidity based on the observed wet bulb and dry bulb temperatures and the elevation at the site of the observation. These can be calculated automatically using Wildland Fire RH Calculator …

Table relative humidity (%) as measured with a psychrometer. Cited reference tables are devices with full (free) ventilation.The complete table for the temperature range from - 30 to 55 ° C and 30 ° C to 350 F.

Relative humidity can be expressed as: φ = (m w / m ws) 100% (2c) where. φ = relative humidity (%) m w = mass of water vapor in the given air volume (kg) m ws = mass of water vapor required to saturate at this volume (kg) Weight of Water Vapor in Air; Relative Humidity Chart - …

This table gives the approximate relative humidity directly from the reading of the air temperature (dry bulb) and the wet bulb. It is computed for a pressure of 74.27 cm Hg.

Mar 5, 2025 · Relative humidity can be determined by measuring the dry bulb and wet bulb temperatures in the field. Using these measured values, the dew point and relative humidity can be determined with the use of tables.
