Convert kilopascals to millimeters of mercury (kPa to mmHg)

Type a value in kilopascals or in millimeters of mercury: the other field updates as you type. Below you will find the formula, a worked example and a kPa to mmHg chart.

1 kPa = 7.50062 mmHg

How to convert kilopascals to millimeters of mercury

Formula: mmHg = kPa × 7.50062

Worked example: 250 kPa → 250 × 7.50062 = 1,875.15 mmHg

Multiply mmHg by 0.133322 to get kilopascals. A blood pressure of 120/80 mmHg is 16.0/10.7 kPa, the form sometimes used in medical literature.

What is a kilopascal?

The kilopascal equals 1,000 pascals. Canadian and many European car manuals give tire pressures in kPa, for example 240 kPa, which is about 35 psi. It is also used in engineering and for blood pressure in some medical texts.

What is a millimeter of mercury?

The millimeter of mercury, about 133.32 pascals, comes from mercury barometers. It remains the unit of blood pressure worldwide: a reading of 120/80 mmHg means a systolic pressure of 120 and a diastolic pressure of 80.

Frequently asked questions

How many millimeters of mercury are in a kilopascal?

A kilopascal equals 7.50062 millimeters of mercury. To convert any value, multiply the number of kilopascals by 7.50062.

How do you convert kilopascals to millimeters of mercury?

Use the formula mmHg = kPa × 7.50062. Example: 250 kPa → 250 × 7.50062 = 1,875.15 mmHg.

How many kilopascals are in a millimeter of mercury?

A millimeter of mercury equals 0.133322 kilopascals. That is the reverse conversion, from millimeters of mercury to kilopascals.
