Do real pilots use QNH to mean altimiter setting?

QNH is ‘nautical height’ so gives you height above sea-level, useful when reading maps whilst VFR.
QFE is ‘field elevation’, so gives you height above the airfield, useful for joining the circuit and landing.

I refuse to believe this is what the Q-codes mean, because they actually make sense.

I mean, it seems like a useful mnemonic, but officially the Q-codes are NOT acronyms and there is not necessarily any correlation between the letters and the meaning.
