What is atmosphere technical (at)?

Atmosphere technical (at) is a legacy non-SI pressure unit defined as one kilogram-force per square centimetre, equal to 98,066.5 pascals.

When is picopascal (pPa) used?

Picopascal measures extremely small pressures, used in fields like advanced vacuum science and space research.

Why convert from atmosphere technical to picopascal?

Conversion allows legacy industrial pressure data to be expressed in very fine units suitable for modern precise scientific measurements.

Tips & Best Practices

Verify the original unit is atmosphere technical (at) before converting.
Be mindful of the large numerical values resulting from conversion due to unit scale differences.
Use picopascal outputs primarily for ultra-low pressure scenarios relevant to scientific research.
Cross-check converted values when interpreting legacy data to avoid computational inaccuracies.

Limitations

The technical atmosphere is a non-SI unit mainly relevant in older contexts, requiring unit confirmation.
Conversion involves very large numbers which may introduce rounding or computational errors.
Picopascal units are only practical for describing ultra-low pressures, not typical industrial levels.
