QFE - The observed pressure at a specified datum (usually aerodrome or runway threshold elevation) corrected for temperature.

QNH - The altimeter sub-scale setting to obtain elevation when on the ground. QNH equals QFE reduced to mean sea level (MSL) pressure using the standard atmosphere lapse rate.
