What is millimeter mercury (0°C)?

It is a pressure unit defined by the pressure exerted by a 1 mm column of mercury at 0 °C under standard gravity, commonly used in clinical and laboratory settings.

Why convert millimeter mercury to picopascal?

Converting millimeter mercury to picopascal allows expressing moderate pressures in terms of extremely fine units used in vacuum science and high-precision measurements.

Are millimeter mercury and picopascal used for similar pressure ranges?

No, millimeter mercury is used for moderate pressures while picopascal measures extremely low pressures, so their practical applications differ.
