SponsoredThis converter turns kilopascals into millimeters of mercury (kPa to mmHg). Enter a value and the result updates as you type. 1 kilopascal is about 7.500616 millimeters of mercury.
Millimeters of mercury are the usual unit for blood pressure, while kilopascals are the SI-based alternative. 1 millimeter of mercury is exactly 133.322387415 pascals, the conventional value based on mercury density and standard gravity. 1 kPa is therefore about 7.5 mmHg, and a blood pressure figure in mmHg is about 7.5 times the same figure in kilopascals.
The result shows 0 for a negative entry, because absolute pressure, counted from a perfect vacuum, cannot be negative. The result is rounded to 3 decimal places.
How to Convert Kilopascals to mmHg
To convert kilopascals to millimeters of mercury, multiply by 1,000 to get pascals, then divide by 133.322387415. For example, 16 kPa is about 120.01 mmHg.
To go from millimeters of mercury back to kilopascals, multiply mmHg by 0.133322387415.

kPa and mmHg in Medicine
Blood pressure readings are given in mmHg. A reading of 120/80 mmHg is about 16/10.7 kPa. The Mean Arterial Pressure Calculator works from systolic and diastolic readings in mmHg, and so does the Cerebral Perfusion Pressure Calculator.
Blood pressure is a gauge pressure, measured above the surrounding air, but the size of one mmHg is the same either way, so the conversion factor does not change.
Frequently Asked Questions
What is 100 kPa in mmHg?
100 kPa is about 750.0616 mmHg. 100 kPa equals exactly 1 bar.
How do I convert mmHg to kPa?
Multiply mmHg by 0.133322387415, or divide by about 7.50062. For example, 760 mmHg is about 101.325 kPa.
What is 101.325 kPa in mmHg?
101.325 kPa, one standard atmosphere, is about 759.9999 mmHg. One standard atmosphere is exactly 760 torr, but the conventional mmHg is very slightly larger than the torr.
Is the Kilopascals to mmHg factor exact?
The reverse direction is exact: 1 millimeter of mercury equals exactly 0.133322387415 kilopascals. In this direction the factor has no finite decimal form, so 1 kilopascal is about 7.500616 millimeters of mercury. The calculator uses the full value and rounds only the result it shows.
What happens if I enter a negative value?
It shows 0. This converter treats both values as absolute pressures, which cannot be negative.
