AbsoluteHumidity is a Chrome extension developed by lyxodius, available for free in the Browsers category under Add-ons & Tools. This extension alters the way humidity information is displayed when searching for 'weather' on Google. Instead of showing relative humidity in percentage values, AbsoluteHumidity provides absolute humidity data.

The rationale behind this extension is to offer more accurate humidity information, considering that air's water-holding capacity varies with temperature. By showing absolute humidity in grams of water per cubic meter of air, users can better assess indoor versus outdoor humidity levels. Note that the extension functions only with English browser settings and degrees centigrade on Google weather searches. For additional features or language support, the developer encourages users to reach out directly.
