What Is This Tool?
This online converter helps you change pressure measurements from newton per square millimeter (N/mm²), a unit often used in materials engineering, into millimeter water (4°C), which is suited for measuring very low pressures in fluid systems.
How to Use This Tool?
-
Enter the pressure value in newton/square millimeter
-
Select newton/square millimeter as the 'From' unit
-
Select millimeter water (4°C) as the 'To' unit
-
Click convert to obtain the equivalent pressure in millimeter water (4°C)
Key Features

0.5 N/mm² converts to 50987.2144461 mm water (4°C)
Common Use Cases
-
Specifying tensile or compressive strengths in engineering materials
-
Translating mechanical stresses into low hydrostatic pressure measurements
-
Calibrating low-range pressure sensors in HVAC or laboratory settings
Tips & Best Practices
-
Verify units carefully due to the large magnitude difference between units
-
Consider temperature and gravity assumptions when using millimeter water (4°C)
-
Use this converter to bridge high-pressure engineering data with precise low-pressure applications
Limitations
-
Large conversion magnitude may require careful handling of scale
-
Millimeter water unit is accurate only at 4°C and assumes standard gravity conditions
Frequently Asked Questions
-
What does a newton per square millimeter measure?
-
It measures pressure or mechanical stress as one newton of force applied over one square millimeter.
-
When is millimeter water (4°C) used?
-
It is used for very small pressure measurements, such as in manometers, sensor calibration, or low-pressure fluid applications.
-
Why is the conversion factor so large?
-
Because 1 newton/square millimeter equals over 100,000 millimeters of water at 4°C, reflecting a large difference in pressure magnitudes.
Key Terminology
-
Newton/square millimeter (N/mm²)
-
A pressure unit representing one newton of force applied over an area of one square millimeter; equivalent to one megapascal.
-
Millimeter water (4°C)
-
A measure of hydrostatic pressure exerted by a 1 mm column of pure water at 4°C under standard gravity, used for very small pressure readings.
