What Is This Tool?

This converter allows you to transform pressure measurements from standard atmosphere (atm) to atmosphere technical (at), facilitating the interpretation between modern and legacy pressure units.

How to Use This Tool?

  • Enter the pressure value in Standard atmosphere (atm)
  • Select 'Standard atmosphere [atm]' as the input unit
  • Choose 'Atmosphere technical [at]' as the target unit
  • Click the convert button to get the equivalent pressure in atmosphere technical

Key Features

  • Converts pressure values from Standard atmosphere (atm) to Atmosphere technical (at)
  • Based on defined conversion rate of 1 atm = 1.0332274528 at
  • Supports applications in chemistry, diving, engineering, and historical data interpretation
  • Browser-based and easy to use for quick unit conversions

Examples

  • 2 Standard atmospheres (atm) converts to approximately 2.0664549056 atmosphere technical (at)
  • 0.5 Standard atmosphere (atm) converts to about 0.5166137264 atmosphere technical (at)

Common Use Cases

  • Reconciling pressure measurements between modern scientific standards and older technical or engineering contexts
  • Interpreting laboratory gas and vacuum pressures in physical chemistry
  • Assessing ambient or depth-related pressure in diving engineering
  • Reviewing historical equipment ratings in boilers, hydraulics, and pneumatic systems
  • Converting legacy pressure values for comparison with SI units

Tips & Best Practices

  • Always verify the context of pressure measurements before conversion
  • Consider the 3.3% difference between units for precision-sensitive tasks
  • Use this converter to assist in interpreting legacy technical documents
  • Cross-check converted values with original data when possible

Limitations

  • Atmosphere technical (at) is a non-SI unit rarely used in modern measurements
  • The slight difference between atm and at requires careful consideration in high-precision applications
  • Conversion accuracy depends on specific use cases and may need rounding

Frequently Asked Questions

What is the standard atmosphere (atm)?
It is a unit of pressure defined as exactly 101,325 pascals, approximating average atmospheric pressure at sea level and used widely in chemical thermodynamics.

What does atmosphere technical (at) represent?
The technical atmosphere is a non-SI pressure unit defined as one kilogram-force per square centimetre, equal to 98,066.5 pascals, commonly used in older engineering specifications.

Why convert between atm and at units?
Conversion helps reconcile modern scientific measurements with older industrial and engineering data that use different pressure units.
