Millimeters of mercury to kilopascals
Type a value in mmHg to get it in kPa instantly.
Nothing on our list is smaller: a vacuum cleaner is 15× higher. Spread over a fingertip, that is like resting 0.0136 kg on it.

What it means
How much pressure is that?
Tyre and tank figures are gauge pressure, measured above the surrounding air. Weather and altitude figures are absolute.
The math
How to convert mmHg to kPa
To convert millimeters of mercury to kilopascals, multiply by 0.133322.
Example: 10 mmHg × 0.133322 = 1.33322 kPa.
In the other direction, 1 kPa = 7.50062 mmHg.

About these units
Millimeters of mercury (mmHg)
One millimeter of mercury is the pressure that holds a 1 mm column of mercury up, about 133 pascals. Blood pressure is still measured this way.
Kilopascals (kPa)
A kilopascal is 1,000 pascals. Car tyres run at roughly 220 kPa, and standard air pressure is 101.3 kPa.
