Large numbers are automatically formatted with thousand separators.
Switch units anytime using the searchable dropdown menus.

mmHg to Torr Formula

The conversion uses a single fixed factor. To go from Millimeter of Mercury to Torr, multiply by the factor below:

Torr = mmHg × 1.0000

To convert back the other way:

mmHg = Torr × 1.0000

Example: 1 mmHg = 1.0000 Torr. Reverse: 1 Torr = 1.0000 mmHg.
