What is a millipascal used for?

A millipascal measures very small pressures typically found in microfluidics, sensitive acoustic calibration, and sub-pascal vacuum detection.

Why is foot water (4°C) used as a pressure unit?

Foot water (4°C) reflects the pressure from a one-foot column of water at 4°C, serving as a standard for hydraulic head and low pressure measurements in fluid systems.

Can I use this conversion tool for high pressure values?

This tool focuses on converting small pressures; using it for very high pressures may reduce accuracy as it is designed for precise, low magnitude pressure ranges.
