Density Altitude

[cointyro]

We know that "Temperature, pressure and humidity determine air density." However when we are at the hot and high airport we find our pressure altitude by turning the altimeter to 29.92 and crosscheck the result with a table with the OAT to get density altitude... we don't consider humidity. Is this because humidity affects the density altitude so little that we can ignore it?

Humidity does effect DA, but it effects it very little compared to pressure and temperature.
