What is one centimeter mercury (0°C) equivalent to in pascals?

It is approximately equal to 1,333.2239 pascals, representing the pressure from a 1 cm mercury column at 0 °C under standard gravity.

Why use micropascal units for pressure?

Micropascal units quantify very small pressures or pressure variations, especially useful in acoustic measurements and sensitive instrumentation.

Can this conversion be used for high pressures?

Micropascal units are best suited for very low pressures; using them for large pressures results in very large numbers and may not be practical.
