Apparent Temperature Calculator

Use a Steadman-style apparent-temperature equation to combine temperature, vapor pressure, and wind.

Air temperature (°C)

Relative humidity (%)

Wind speed

Wind unit

—Apparent temperature

—Vapor pressure

—Wind used

—Apparent − air temp

Uses the shade-based Steadman apparent-temperature form AT = T + 0.33e − 0.70v − 4. Sun exposure, clothing, activity, and local conditions are not represented.
