What Is This Tool?
This converter allows users to translate pressure measurements from the historical technical atmosphere unit (at) to the foot water unit at 60°F (ftAq). It’s designed for converting legacy pressure values into low-pressure hydrostatic measurements commonly used in HVAC, hydraulics, and laboratory settings.
How to Use This Tool?
-
Enter the pressure value in atmosphere technical [at].
-
Select atmosphere technical [at] as the source unit.
-
Choose foot water (60°F) [ftAq] as the target unit.
-
Click the convert button to get the equivalent pressure.
-
Review the converted hydrostatic pressure in foot water (60°F).
Key Features
-
Converts pressure units from atmosphere technical [at] to foot water (60°F) [ftAq].
-
Supports legacy engineering and industrial pressure data translation.
-
Browser-based and easy to use without installation.
-
Provides clear conversion examples with formulas.
-
Helps compare and understand low-pressure hydrostatic values in modern contexts.
Examples
-
2 atmosphere technical [at] equals 65.6816413026 foot water (60°F) [ftAq].
-
0.5 atmosphere technical [at] equals 16.4204103257 foot water (60°F) [ftAq].
Common Use Cases
-
Interpreting legacy pressure ratings in older industrial equipment.
-
Measuring low-pressure differentials in HVAC and building ventilation systems.
-
Assessing hydraulic head or pressure drops in small pumps and filters.
-
Testing gas distribution pressures and leak detection.
-
Translating historical engineering data into modern SI-compatible units.
Tips & Best Practices
-
Ensure pressures are originally measured in technical atmospheres for accurate conversion.
-
Use this tool mainly when working with historical or legacy pressure data.
-
Remember foot water pressure values assume a water temperature of 60°F and standard gravity.
-
Verify local conditions if precision in low-pressure measurements is crucial.
-
Refer to conversion formulas provided for manual calculations if needed.
Limitations
-
Technical atmosphere is a non-SI unit and less common in modern measurements.
-
Foot water pressure is temperature-dependent, based on 60°F standard conditions.
-
Conversions may vary if local temperature or gravity conditions differ from assumptions.
-
Careful interpretation is necessary when using legacy unit values in contemporary contexts.
Frequently Asked Questions
-
What is a technical atmosphere (at)?
-
The technical atmosphere is a non-SI pressure unit defined as one kilogram-force per square centimetre, equal to 98,066.5 pascals.
-
When should I convert from atmosphere technical to foot water?
-
This conversion is useful for interpreting older engineering pressure values and comparing them to low-pressure hydrostatic measurements used in HVAC and laboratory systems.
-
Does foot water pressure value depend on temperature?
-
Yes, foot water pressure is specified at 60°F, so temperature variations may affect conversion accuracy.
Key Terminology
-
Atmosphere Technical [at]
-
A non-SI pressure unit equal to one kilogram-force per square centimetre, used in historical engineering contexts.
-
Foot Water (60°F) [ftAq]
-
A pressure unit based on the hydrostatic pressure of a 1-foot column of water at 60°F under standard gravity conditions.
-
Hydrostatic Pressure
-
Pressure exerted by a fluid at equilibrium due to the force of gravity.
