Transition Altitude and Levels

Transition altitudes with corresponding Transition levels:

Left column shows intervals of local pressure (QNH) in hecto Pascal (millibar). Corresponding local pressure in inches of mercury is found in the right-most column. The other columns show the Transition altitude at top and below are the corresponding Transition levels depending on QNH.
