Abstract

It is known that conventional methods for determining atmospheric pressure by measuring the length-height of the mercury column in Torriceli's Tube (TT) give resolution up to 1 Pa. A method is presented in this note for determining atmospheric pressure by measuring mercury column mass in TT which facilitates measurement with a resolution up to 0.01 Pa; this is approximately 100 times the resolution afforded by conventional methods.

The application of this method requires measurement equipment available in a large number of laboratories worldwide, and it may be used in different areas of scientific research, using various measurement techniques and in experimental physics.
