1 atm equals how many torr?

Explanation:
Pressure units connect atmospheres to torr and mmHg through a standard definition. 1 atm is defined as 760 torr, and a torr is defined as 1 mmHg. Since 1 atm = 760 mmHg as well, it follows that 1 atm = 760 torr. Therefore the value in torr is 760. (760 mmHg would express the same pressure in the mmHg unit, since torr and mmHg are equivalent.)
