How to convert millimeter of mercury to atmosphere

One millimeter of mercury equals 0.001315789661 atm, so multiply the number of millimeter of mercurys by 0.001315789661:

atm = mmHg × 0.001315789661

Going the other way

One atmosphere equals 759.9998917 mmHg, so to convert back:

mmHg = atm × 759.9998917

Both directions are shown in the results above, and the drop-downs let you convert between any pair of pressure units — not just these two.
