mmHg to Pa Converter - Millimeters of Mercury to Pascal

Millimeters of Mercury (mmHg) to Pascal (Pa)

Direct answer

1 mmHg = 133.322 Pa

Pa = mmHg × 133.322

Converter

Input

mmHg

Result

133.322Pa

Pa = mmHg × 133.322

mmHg = Pa × 0.007500637554

Example: 10 mmHg = 10 × 133.322 = 1,333.22 Pa.

Express both mmHg and Pa 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 Pa in the base unit
$1 Pa = 1 Pa$
3
Forward conversion
$1 mmHg = \frac{133.322 Pa}{1 Pa} \times 1 Pa = \frac{133.322}{1} Pa = 133.322 Pa$
4
Reverse conversion
$1 Pa = \frac{1 Pa}{133.322 Pa} \times 1 mmHg = \frac{1}{133.322} mmHg = 0.007500637554 mmHg$
