Use the tool for pressures where non-SI unit approximations are acceptable
-
Consider the temperature dependency when interpreting centimeter water (4°C) values
-
Apply conversions for low-pressure measurements typical of medical and lab contexts
-
Reference legacy documentation thoughtfully when transitioning to hydrostatic units
Limitations
-
Both pressure units are non-SI and rely on approximations near 98.0665 pascals
-
Temperature changes can impact the centimeter water (4°C) measurement accuracy
-
Not recommended for applications requiring strict high-precision pressure values
Frequently Asked Questions
-
Why use gram-force per square centimeter instead of SI units?
-
Gram-force per square centimeter is used in contexts involving legacy units and gravitational force definitions, especially in some older engineering and laboratory standards.
-
What is centimeter water (4°C) used for?
-
Centimeter water (4°C) expresses small pressures and differences, commonly used in medical respiratory care and laboratory measurements involving hydrostatic pressure.
-
Can this converter be used for high-precision pressure measurements?
-
No, since both units are approximations close to 98.0665 pascals and are non-SI, caution is advised for high-precision applications.
Key Terminology
-
Gram-force per square centimeter
-
A pressure unit based on the force of one gram-force applied over one square centimeter, relying on gravitational force and used in legacy pressure measurements.
-
Centimeter water (4°C)
-
A pressure unit defined as the hydrostatic pressure from a 1 cm column of pure water at 4°C, commonly used in medical and lab small-pressure contexts.
-
Non-SI unit
-
Units of measurement that are not part of the International System of Units, often based on older or practical definitions.
