What does one newton per square millimeter represent?

It is a pressure unit denoting one newton of force applied over an area of one square millimeter, equivalent exactly to one megapascal.

What is centimeter mercury (0°C) and where is it used?

Centimeter mercury (0°C) is a pressure measure based on the height of a mercury column at 0 degrees Celsius under standard gravity, often used for laboratory manometer readings and sensor calibration.

Why must standard gravity and temperature be considered during conversion?

Because the conversion relies on mercury pressure exerted under specific conditions (0°C and 9.80665 m/s² gravity), variations in these factors can affect accuracy.
