On a rainy day, a barometer reads 727 mmHg. Convert this value to atmospheres.
Express your answer numerically in atmospheres.
Gases exert a measurable pressure (P) on the walls of their container. The SI unit for pressure is the pascal (Pa). Other pressure units frequently used in chemistry are millimeters of mercury (mmHg) and atmospheres (atm). You can convert between units of pressure using conversion factors such as those indicated below . 1 atm = 760 mmHg = 101, 325 Pa
