-
A value of 100 femtopascal equals 1.0197162129779e-14 kilogram-force per square meter.
Common Use Cases
-
Describing ultra-low gas pressures in interstellar or interplanetary space.
-
Expressing residual pressures in ultra-high-vacuum physics experiments.
-
Converting legacy engineering pressure records from gravitational metric units.
-
Interpreting older technical literature or regional documents using kgf/m² units.
Tips & Best Practices
-
Ensure correct unit selection to avoid conversion errors.
-
Use this conversion for interpreting very small pressure values with high precision.
-
Refer to legacy documentation context when applying values in kgf/m².
-
Cross-check results when integrating data from scientific and historical sources.
Limitations
-
Results involve extremely small decimal values due to vast difference in unit scales.
-
Requires high precision handling for meaningful interpretation.
-
Kilogram-force per square meter is not an SI unit and may be uncommon in current scientific use.
Frequently Asked Questions
-
What is a femtopascal used for?
-
Femtopascal measures extremely low pressures, often used in astrophysics or ultra-high-vacuum science to describe very small forces per unit area.
-
Why convert femtopascal to kilogram-force per square meter?
-
Conversion helps translate ultra-low scientific pressure measurements into legacy or regional engineering units for comparison and analysis.
-
Is kilogram-force per square meter an SI unit?
-
No, kilogram-force per square meter is a non-SI unit historically used in engineering and industrial contexts.
Key Terminology
-
Femtopascal (fPa)
-
A unit equal to 10⁻¹⁵ pascals used to measure extremely low pressures, mainly in scientific and astrophysical fields.
-
Kilogram-force per square meter (kgf/m²)
-
A non-SI pressure unit representing the force of one kilogram-force evenly applied over one square meter, equal to 9.80665 pascals.
-
Pressure
-
The force applied per unit area, expressed in various units depending on the context or field.
