Limitations
-
Permeability inches (0°C) depend on a specific temperature (0°C) and inch-based pressure units which may limit use in other temperature or pressure contexts
-
Non-SI nature of permeability inches (0°C) can restrict its acceptance in strictly SI unit-based scientific publications
-
Care is needed to avoid misinterpretation when applying this unit outside its standard reference conditions
Frequently Asked Questions
-
What does kilogram per pascal second square meter measure?
-
It is an SI-derived unit expressing permeability related to flow resistance or the inverse of hydraulic conductivity in porous media and membrane systems.
-
Why use permeability inches (0°C) instead of SI units?
-
Permeability inches (0°C) relate permeability to pressure differences measured in inches of water column at 0°C, making it practical for certain industry tests and standards.
-
Can I use this converter for any temperature?
-
No, permeability inches (0°C) are defined specifically with a 0°C pressure reference; using them at different temperatures may cause inaccuracies.
