Convert mmHg to Pascals

1 mmHg = 133.32 Pa

1 mmHg = 133.32 Pa

mmHg (mmHg) pascals (Pa)
0.5 66.661
1 133.32
2 266.64
5 666.61
10 1333.22
25 3333.05
50 6666.1
100 13332.2
250 33330.5
500 66661
1000 133322

To convert mmHg to pascals, multiply the value by the conversion factor:

1 mmHg = 133.32 Pa

For example: 10 mmHg = 1333.22 Pa

The Conversion Formula

To convert mmHg to pascals, multiply the value by the conversion factor: 1 mmHg = 133.32 Pa. For a worked example, suppose you need to convert 25 mmHg to pascals: 25 × 133.32 = 3333.05 Pa. To convert in the opposite direction, divide by 133.32, or equivalently multiply by 0.00750064.

About mmHg

This unit literally measures pressure by how many millimeters it can push a column of liquid mercury up a tube. It dates back to the first barometers in the 1600s. Despite being archaic, it is the absolute global standard for measuring blood pressure. When a doctor says '120 over 80', they mean mmHg. mmHg are commonly used in Blood pressure, Meteorology, Vacuum pumps, and Laboratory physics, Medicine.

Normal systolic blood pressure is around 120 mmHg.

About pascals

The pascal (Pa) is the SI unit of pressure, named after French polymath Blaise Pascal. One pascal is one Newton of force per square meter. It is a very small unit—atmospheric pressure is over 100,000 pascals! Because it's so small, meteorologists and engineers often prefer kilopascals (kPa) or hectopascals (hPa). pascals are commonly used in Scientific research, Acoustics (Sound pressure), Ventilation systems (very low pressure), and Clean room standards, Geophysics.

The pressure of a dollar bill on a table is roughly 1 Pascal.

When Would You Convert mmHg to pascals?

Converting between mmhg and pascals is one of the most common pressure conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 mmHg = 133.32 Pa) memorized or bookmarked can save time in professional and everyday contexts alike.
