What does inch mercury (60°F) represent?

It is a pressure unit based on the hydrostatic pressure exerted by a one-inch column of mercury at 60°F, ensuring consistent calibration.

Why use standard atmosphere for pressure?

Standard atmosphere is a defined unit representing average sea-level atmospheric pressure, making it useful for scientific and engineering comparisons.

Can temperature affect the conversion?

Yes, since inch mercury (60°F) relies on mercury density fixed at 60°F, temperature deviations can impact measurement accuracy.
