What Is This Tool?

This converter helps translate pressure measurements from millimeter water (4°C), a unit for very small pressures, into atmosphere technical [at], a non-SI unit historically used in engineering and industrial fields.

How to Use This Tool?

  • Enter the pressure value in millimeter water (4°C)
  • Select 'millimeter water (4°C)' as the source unit
  • Choose 'atmosphere technical [at]' as the target unit
  • Click convert to get the pressure in atmosphere technical [at]

Key Features

  • Converts low-pressure values from millimeter water (4°C) to atmosphere technical [at]
  • Ideal for interpreting legacy pressure data and equipment specifications
  • Browser-based and easy to use without installation

Examples

  • 10 millimeter water (4°C) converts to 0.000999972 atmosphere technical [at]
  • 500 millimeter water (4°C) converts to 0.0499986 atmosphere technical [at]

Common Use Cases

  • Measuring very low pressures in HVAC systems and cleanroom differentials
  • Calibrating low-range pressure sensors and conducting laboratory experiments
  • Converting legacy pressure readings in boiler, hydraulic, and pneumatic equipment

Frequently Asked Questions

What does millimeter water (4°C) represent?
It represents the hydrostatic pressure from a 1 mm column of pure water at 4 °C under standard gravity, used for very small pressure measurements.

Why convert to atmosphere technical [at]?
Because it is a non-SI unit used in historical engineering and industrial contexts, useful for interpreting older specifications and equipment data.

Can this conversion be used for high pressures?
No, millimeter water (4°C) is intended for very low pressures and may not be suitable or precise for large pressure values.

Key Terminology

Millimeter water (4°C)
A pressure unit representing the hydrostatic pressure from a 1 mm column of pure water at 4 °C under standard gravity.
Atmosphere technical [at]
A non-SI pressure unit defined as one kilogram-force per square centimetre, used historically in engineering contexts.
