mmHg to kPa Converter - Millimeters of Mercury to Kilopascal

Millimeters of Mercury (mmHg) to Kilopascal (kPa)

Direct answer

1 mmHg = 0.133322 kPa

kPa = mmHg × 0.133322

Converter

Input

mmHg

Result

0.133322kPa

kPa = mmHg × 0.133322

mmHg = kPa × 7.50063755419

Example: 10 mmHg = 10 × 0.133322 = 1.33322 kPa.

Express both mmHg and kPa 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 kPa in the base unit
$1 kPa = 1, 000 Pa$
3
Forward conversion
$1 mmHg = \frac{133.322 Pa}{1 , 000 Pa} \times 1 kPa = \frac{133.322}{1 , 000} kPa = 0.133322 kPa$
4
Reverse conversion
$1 kPa = \frac{1 , 000 Pa}{133.322 Pa} \times 1 mmHg = \frac{1 , 000}{133.322} mmHg = 7.50063755419 mmHg$
