What Is This Tool?
This converter allows you to change permeability measurements expressed as Permeability inches (23°C) into Permeability (23°C), enabling comparison of materials' intrinsic vapor or gas transmission abilities at a steady 23 °C temperature.
How to Use This Tool?
-
Enter the permeability value in Permeability inches (23°C).
-
Select the target unit as Permeability (23°C).
-
Click convert to obtain the equivalent permeability coefficient at 23 °C.
Key Features
-
Converts permeability values normalized by specimen thickness in inches to permeability coefficients at 23 °C.
-
Useful for building materials, packaging films, membranes, and barrier materials evaluation.
-
Standardizes permeability units for easier comparison across different applications and industries.
Examples
-
Convert 10 Permeability inches (23°C) to get 0.253999391 Permeability (23°C).
-
Convert 5 Permeability inches (23°C) resulting in 0.1269996955 Permeability (23°C).
Common Use Cases
-
Specifying and comparing vapor retarders and insulation materials for building envelopes.
-
Evaluating polymer packaging films for water vapor or gas barrier performance.
-
Selecting membranes or gasket materials in engineering to meet design or regulatory needs.
Tips & Best Practices
-
Ensure all permeability measurements are taken at exactly 23 °C for consistency.
-
Use this conversion to standardize permeability data for design or compliance analysis.
-
Compare materials’ barrier performance independent of thickness by using permeability coefficients.
Limitations
-
Conversion only applies at the reference temperature of 23 °C; other temperatures may affect results.
-
Measurement variations and unit differences may require further standardization beyond conversion.
Frequently Asked Questions
-
Why is it important to convert permeability inches (23°C) to permeability (23°C)?
-
Converting these units allows comparison of materials’ intrinsic barrier properties independent of specimen thickness and standardizes data across industries.
-
Can this conversion be used for temperatures other than 23 °C?
-
No, this conversion assumes measurements at 23 °C; deviations may affect permeability values and require different calculations.
-
What industries commonly use this permeability conversion?
-
Construction, polymer packaging development, membrane engineering, and electronics encapsulant selection frequently use this conversion.
Key Terminology
-
Permeability inches (23°C)
-
A measurement expressing material vapor or gas transmission as permeance times thickness in inches, standardized at 23 °C.
-
Permeability (23°C)
-
The permeability coefficient quantifying intrinsic transmission ability per unit partial-pressure difference at 23 °C.
-
Permeance
-
The rate at which a vapor or gas passes through a material, often multiplied by thickness to derive permeability inches.
