What does millimeter water (4°C) represent?

It is the pressure exerted by a 1 mm column of pure water at 4 °C under standard gravity, used for measuring very low pressures.

What is ksi and where is it commonly used?

Ksi, or kilopound per square inch, is a unit of pressure used mainly in materials and structural engineering to express stress or strength values.

Why convert millimeter water (4°C) to ksi?

To relate low hydrostatic pressure measurements to engineering stress values, facilitating comparisons and integrations in structural and mechanical engineering.

Examples

10 millimeter water (4°C) converts to approximately 0.000014222951705207 ksi.
100 millimeter water (4°C) converts to roughly 0.00014222951705207 ksi.

Common Use Cases

Measuring low pressure differences in HVAC static pressure and cleanroom environments.
Calibrating low-range pressure sensors in laboratory experiments.
Designing plumbing or drainage systems where small pressure drops are critical.
Expressing material stress limits in mechanical, structural, and civil engineering.

Tips & Best Practices

Ensure that your pressure values are applicable to hydrostatic or low-pressure scenarios before converting.
Use this conversion when comparing low-pressure measurements to material stress properties expressed in ksi.
Be aware that ksi results from small pressure inputs will be very low and may require sensitive instruments for further practical use.

Limitations

Millimeter water (4°C) is suited for very small pressures while ksi represents much larger stresses, so results are often extremely small numbers.
Not suitable for high pressure ranges or conditions that are not hydrostatic.
Conversion values may need high precision for meaningful interpretation in some engineering applications.
