First - the issue of "vertical units" - how high...?
xxx
If your altimeter is on QNH, you are in
altitude...
If your altimeter is on QNE (1013.2/29.92). you are in
level...
You good little boys know the above.
If you use QFE, your altimeter is in
height...!

That is the way you speak to ATC, either level, altitude or height.
Do not confuse the three when doing checklists/SOPs in the flight deck.

Altimeter transitions therefore become -
Transition altitude (climbing), when changing from QHH to QNE...
Transition level (descending), changing from QNE to QNH (or QFE like in Russia)...
Transition height (climbing), changing from QFE to QNE (as you do in Russia)...

Units used -
Russians use hPA on their international airports. Domestic sometimes use mm/Hg.
29.92 in/Hg = 1013.2 mB (or hPa) = 760 mm/Hg.
Inches and millimeters are
length units while hPA/mB is a
pressure unit.
No need to review feet and meters... I guess everyone knows them.

QFE notes -
A QFE for precision approach (ILS) is based on TDZE... expressed in meters in Russia.
A QFE for non-precision (circle to land) is based on airport elevation.
Expect a downwind to be 500 meters AGL in Russia when flying QFE.

Jeppesen publishes QNH and QFE on
all approach, SIDs and STARs ICAO worldwide charts.
The QNH altitudes are in plain numbers, the QFE heights are in parenthesis.
I.e. runway TDZE 521 ft AGL, your decision altitude/height might be shown as 721' (200').

My QFE briefing is an 8 hrs classroom curriculum -
In simulator, for practice, I require a QFE procedure for the all-engines ILS.
No extra simulator time...
After I retire next month, I am available to come and teach. I am expensive.
$500 per day, or fraction of day... and you pay the beers for debriefing.
