Flow widget to calculate Transition Levels based on local QNH and Transition Altitude
Clicking the Tile will open a conversion table, based off this one:

There's also an Otto command where you can enter your own values, with an optional Transition Layer that is added ontop of the Transition Altitude:
trl <QNH> <Transition Altitude> [transition layer]
For example:
trl 1023 4500
or:
trl 1002 5000 1000
