Tips & Best Practices
-
Review legacy equipment specifications carefully to confirm unit usage
-
Use scientific notation to manage extremely large numerical results
-
Consider the non-SI nature of technical atmospheres when applying results
-
Apply sensitive instrumentation for pressures expressed in femtopascal due to their ultra-low magnitude
Limitations
-
Technical atmosphere is a non-SI unit potentially introducing approximation errors
-
Femtopascal represents pressures far smaller than typical industrial pressures
-
Conversion involves very large numbers, requiring scientific notation and careful handling
-
Practical measurement of femtopascal pressures demands highly sensitive instruments
Frequently Asked Questions
-
What is an atmosphere technical [at] unit?
-
It is a non-SI pressure unit defined as one kilogram-force per square centimetre, equal to 98,066.5 pascals and approximately 0.96784 standard atmospheres.
-
When should I use femtopascal [fPa] units?
-
Femtopascal is used to express extremely small pressures such as those found in interstellar space or ultra-high vacuum experiments.
-
Why convert from atmosphere technical to femtopascal?
-
This conversion helps translate older industrial pressure measurements into ultra-small scientific units for precise analysis and comparison.
