mmHg to bar Converter - Millimeters of Mercury to Bar

Millimeters of Mercury (mmHg) to Bar (bar)

Direct answer

1 mmHg = 0.00133322 bar

bar = mmHg × 0.00133322

Converter

Input

mmHg

Result

0.00133322bar

bar = mmHg × 0.00133322

mmHg = bar × 750.063755419

Example: 10 mmHg = 10 × 0.00133322 = 0.0133322 bar.

Express both mmHg and bar in the same base unit Pa (pascal), then cancel the shared base unit.

1
Rewrite mmHg in the base unit
$1 mmHg = 133.322 Pa$
2
Rewrite bar in the base unit
$1 bar = 100, 000 Pa$
3
Forward conversion
$1 mmHg = \frac{133.322 Pa}{100 , 000 Pa} \times 1 bar = \frac{133.322}{100 , 000} bar = 0.00133322 bar$
4
Reverse conversion
$1 bar = \frac{100 , 000 Pa}{133.322 Pa} \times 1 mmHg = \frac{100 , 000}{133.322} mmHg = 750.063755419 mmHg$
