What does millimeter mercury (0°C) represent?

It is a pressure unit defined by the pressure a 1 mm column of mercury exerts at 0°C under standard gravity.

Why convert mmHg to Standard atmosphere?

Converting to Standard atmosphere allows pressure values to be compared and used in scientific and engineering calculations referencing a common standard.

Does Standard atmosphere change with altitude?

No, Standard atmosphere is a fixed unit exactly equal to 101,325 pascals and does not vary with local atmospheric conditions.
