What is atmosphere technical [at] used for?

It is primarily used in older engineering contexts for specifying pressure in kilogram-force per square centimetre, such as in legacy boilers and hydraulic systems.

Why convert atmosphere technical [at] to inch water (4°C) [inAq]?

Converting to inch water allows users to express pressure with finer resolution suitable for low-pressure measurements common in HVAC and lab environments.

Does temperature affect inch water (4°C) pressure measurements?

Yes, inch water pressure is defined specifically at 4 °C, so temperature variations can impact the measurement accuracy.
