One torr equals approximately 133.322 pascals. This is nearly the same as one millimeter of mercury (mmHg).
Multiply the torr value by 133.322. For example, 760 torr × 133.322 = 101,325 Pa (1 atmosphere).
Very nearly. One torr is defined as 1/760 of a standard atmosphere, while 1 mmHg is defined by the density of mercury. They differ by less than 0.000015%, so they are used interchangeably.
Rough vacuum is 760-25 torr, medium vacuum 25-0.001 torr, high vacuum below 10^-3 torr, and ultra-high vacuum below 10^-9 torr.
