Frequently Asked Questions
-
Why convert from gram-force/sq. centimeter to picopascal?
-
Converting to picopascal allows precise scientific analysis by translating legacy gravitational force–based pressure measurements into accurate SI-derived pressure units.
-
What contexts use picopascal units?
-
Picopascal units are used for very low pressure measurements such as residual gas pressures in vacuum chambers and ambient pressures in space environments.
-
Are there any challenges in using gram-force/sq. centimeter?
-
Yes, since gram-force/sq. centimeter relies on local gravity, it may produce inconsistent results depending on location, and handling large numbers can be complex.
Key Terminology
-
Gram-force/sq. centimeter
-
A non-SI pressure unit representing force of one gram-force applied over one square centimeter, based on gravitational force.
-
Picopascal [pPa]
-
An SI-derived pressure unit equal to 10⁻¹² pascals, used to quantify extremely small forces per unit area.
-
Pascal (Pa)
-
The SI unit of pressure defined as one newton per square meter.
