What is a nanopascal used for?

A nanopascal measures extremely small pressures and is commonly used in scientific fields like space physics and ultra-high vacuum systems.

Why use millimeter water (4°C) for pressure measurement?

Millimeter water (4°C) represents hydrostatic pressure from a water column at maximum density temperature, suitable for low-pressure instrumentation and calibration.

Is this conversion precise for all pressure ranges?

The conversion is intended for very low pressures; due to the small magnitude difference, it is not suitable for higher pressure values.
