With this calculator, kPa to mmHg conversion has never been easier. Our kPa to mmHg converter is invaluable when you want to instantly convert your values between kPa and mmHg pressure units and vice versa.

But that's not all: we often write pressure values in different units, so our calculator offers the ability to convert between many of them.

Read the short article below and let us explain what kPa to mmHg conversion is, and what is the formula for kPa to mmHg conversion.

Convert kPa to mmHg

The millimeter of mercury (mmHg) is a non-SI unit of pressure equal to the pressure exerted by a column of mercury one millimeter high at 0°C.

The Pascal (symbol Pa), on the other hand, is an SI unit of pressure equal to one newton per square meter. In the SI, the prefix "kilo" represents a factor of 103, so
1 kilopascal=103 pascals1\ \text{kilopascal} = 10^{3}\ \text{pascals}.

To convert kPa to mmHg, use the following kPa to mmHg formula:

mmHg=kPa×7.50062\text{mmHg} = \text{kPa} \times 7.50062

Now let's check kPa to inHg conversion (inches of mercury):

inHg=kPa×0.296133971\text{inHg} = \text{kPa} \times 0.296133971

In the other direction, we can convert the pressure measured in mmHg to kilopascals using the following mmHg to kPa conversion factor:

kPa=mmHg×0.133322\text{kPa} = \text{mmHg} \times 0.133322

kPa to mmHg conversion: examples

It's time for a little practice - 7 kilopascals to mmHg conversion runs:

7 kPa=7×7.50062=52.5043 mmHg\begin{align*} \rm 7 \text{ } kPa &= \rm 7 \times 7.50062 \\ \rm &= \rm 52.5043\text{ } mmHg \\ \end{align*}

Similarly, let's do a 7 kPa to inHg conversion:

7 kPa=7×0.296133971=2.0671 inHg\begin{align*} \rm 7 \text{ } kPa &= \rm 7 \times 0.296133971 \\ \rm &= \rm 2.0671\text{ } inHg \\ \end{align*}

Let's use the formulas we've learned to convert 30 mmHg to kPa:

30 mmHg=30×0.133322=3.99967 kPa\begin{align*} \rm 30 \text{ } mmHg &= \rm 30 \times 0.133322 \\ \rm &= \rm 3.99967\text{ } kPa \\ \end{align*}

How to use this kPa to mmHg conversion calculator

Using our kPa to mmHg converter is child's play:

  1. Type your pressure value in kPa.
  2. The kilopascals to mmHg conversion will happen in a flash and our tool will give you the corresponding pressure value in mmHg.
  3. You can also use this converter as mmHg to kPa conversion calculator and give the pressure in mmHg first.
  4. Select different pressure units (we have a lot of them!) by clicking the unit label in any field.

How many mmHg is 101.325 kPa?

760 mmHg. To convert 101.325 kPa to mmHg:

  1. Use the kPa to mmHg formula:
    mmHg = kPa × 7.50062.
  2. Enter the pressure in kPa:
    mmHg = 101.325 × 7.50062 = 760 mmHg.
  3. Congrats, you've received 760 mmHg, which is another unit of pressure: 1 atm.

How can I convert mmHg to kPa?

To convert from mmHg to kPa:

  1. Take your pressure value in mmHg.
  2. Multiply it by 0.133322.
  3. Get pressure in kPa.

For example, let's calculate what is 35 mmHg (partial pressure of carbon dioxide within arterial or venous blood) in kPa:
35 × 0.133322 = 4.66628 kPa.
