How do you calculate torr pressure?
Torr is a pressure unit which is defined as 1 standard atmosphere divided by 760 (1 atm/760 or 101325 Pa/760). Used mostly for measuring high vacuum, the torr has largely been superseded by the hPa (mbar) pressure unit. 1 torr equals 133.322 pascals.
How do you convert mmHg to torr?
