What is a femtopascal?

A femtopascal is a very small pressure unit equal to 10⁻¹⁵ pascals, used to measure ultra-low pressures such as those in interstellar space.

What does millimeter mercury (0°C) measure?

Millimeter mercury (0°C) is a pressure unit based on the pressure exerted by a 1 mm column of mercury at 0 °C under standard gravity.

Why convert femtopascal to millimeter mercury?

Converting helps translate extremely low scientific pressures into a more conventional unit used in clinical and laboratory contexts.
