Frequently Asked Questions
-
What does kilogram-force per square millimeter measure?
-
It measures pressure or stress by applying one kilogram-force over an area of one square millimeter, used mainly in materials testing and engineering.
-
Why is millimeter mercury (0°C) used in clinical measurements?
-
Because it corresponds to the pressure exerted by a 1 mm mercury column at 0 °C, it is commonly used in devices like sphygmomanometers to measure blood pressure.
-
Can I use this conversion tool for vacuum pressure readings?
-
Yes, millimeter mercury (0°C) is often used to report moderate vacuum and barometric pressures in engineering fields.
-
Does local gravity affect the accuracy of kilogram-force/sq. millimeter?
-
Yes, because kilogram-force units depend on gravitational force, variations in local gravity can slightly affect measurements.
Key Terminology
-
Kilogram-force per square millimeter (kgf/mm²)
-
A non-SI unit of pressure equal to one kilogram-force applied to an area of one square millimeter, often used in tensile strength measurement.
-
Millimeter mercury (mmHg)
-
A pressure unit defined by the pressure exerted by a 1 mm column of mercury at 0 °C under standard gravity, used frequently in medical and laboratory contexts.
-
Conversion Rate
-
The factor used to translate pressure values between kilogram-force/sq. millimeter and millimeter mercury (0°C), specifically 1 kgf/mm² = 73,556.127270818 mmHg.
