What is a torr and where is it commonly used?

A torr is a unit of pressure equal to 1/760 of a standard atmosphere, used mainly for measuring low pressures in vacuum systems, semiconductor fabrication, and scientific instruments.

Why convert torr to centimeter mercury (0°C)?

Converting torr to centimeter mercury (0°C) translates vacuum pressure readings into an equivalent mercury column height, facilitating comparison and calibration of instruments that use mercury manometers.

Are there any factors that affect the accuracy of this conversion?

Yes, variations in temperature and gravity, which influence mercury density and hydrostatic pressure, can cause slight discrepancies in the conversion accuracy.
