kPa To mmHg Calculator: Convert Kilopascals To millimeter Hg (+Chart)

When it comes to pressure units, you might need to convert kPa to mmHg. Basically, we are converting kilopascals to millimeters of Hg (mercury). To help you out with this conversion, we created a kPa to mmHg calculator, along with the 1-1000 kPa to Hg conversion chart (below the calculator):

 

Let’s look at one example to illustrate how this online calculator works:

Say you want to convert 15 kPa to mmHg. You just insert ’15’ in the kPa input field, hit ‘Calculate’, and you get this result (screenshot):

We can see right away that 15 kPa is equal to 112.51 mmHg.

Let’s look at the math behind this conversion:

How Do You Convert kPa To mmHg?

kPa to mmHg is an easy conversion because we only need to know this relationship:

1 kPa = 7.50061683 mmHg

Namely, 1 kPa is equal to about 7.5 mmHg. Based on this, we can write the following kPa to mmHg formula:

mmHg = kPa × 7.50061683

We see that, in order to convert kPa to mmHg, we only need to multiply kPa by 7.50061683 factor.

Quick Example: How many mmHg is 50 kPa? Simple. We just insert 50 kPa in the equation above and calculate the mmHg pressure like this (with the result):

mmHg  (50 kPa) = 50 kPa × 7.50061683 = 375.03 mmHg

We can see that 50 kPa is equal to 375.03 mmHg.

This is just one example. To help you out, we have created the following kPa to mmHg conversion chart, ranging from 1 kPa to 1000 kPa with mmHg equivalents:
