mmHg to mbar Converter - Millimeters of Mercury to Millibar

Millimeters of Mercury (mmHg) to Millibar (mbar)

Direct answer

1 mmHg = 1.33322 mbar

mbar = mmHg × 1.33322

Converter

Input

mmHg

Result

1.33322mbar

mbar = mmHg × 1.33322

mmHg = mbar × 0.750063755419

Example: 10 mmHg = 10 × 1.33322 = 13.3322 mbar.

Express both mmHg and mbar 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 mbar in the base unit
$1 mbar = 100 Pa$
3
Forward conversion
$1 mmHg = \frac{133.322 Pa}{100 Pa} \times 1 mbar = \frac{133.322}{100} mbar = 1.33322 mbar$
4
Reverse conversion
$1 mbar = \frac{100 Pa}{133.322 Pa} \times 1 mmHg = \frac{100}{133.322} mmHg = 0.750063755419 mmHg$
