Mean arterial pressure calculator

The calculator computes mean arterial pressure: (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not change MAP. In the first example the result is 90 mmHg.

The calculator does not diagnose hypertension and does not replace a clinic reading. The calculator computes mean arterial pressure: (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not change MAP.

How it works

The calculator uses the numbers you enter. The calculator computes mean arterial pressure: (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not change MAP. In the first example the result is 90 mmHg.

The five form fields are Systolic BP, Diastolic BP, Age, BMI, and Resting heart rate. Mean arterial pressure means: This is the main result on this page. In the first example it is 90 mmHg. Systolic BP means: The first form field. It enters the formula or sits beside the result. The calculator computes mean arterial pressure: (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not change MAP. Diastolic BP means: The second form field. The calculator does not diagnose hypertension and does not replace a clinic reading.

The second example gives 100 mmHg. The third example gives 83 mmHg. The calculator computes mean arterial pressure: (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not change MAP. In the first example the result is 90 mmHg.

The calculator does not diagnose hypertension and does not replace a clinic reading.

Enter 118, 76, 42, 24.5, 68, then click Calculate. A comma in 12.5 is read the same way as a period. Fields on a 0-10 scale are notes and are not the primary result unless this page formula says so.

How is the result calculated?

The calculator computes mean arterial pressure: (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not change MAP.

What does the calculator not do?

The calculator does not diagnose hypertension and does not replace a clinic reading.

What do Mean arterial pressure, Systolic BP (mmHg), and Diastolic BP (mmHg) mean?

This is the main result on this page. In the first example it is 90 mmHg. The first form field. It enters the formula or sits beside the result. The calculator computes mean arterial pressure: (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not change MAP. The second form field. The calculator does not diagnose hypertension and does not replace a clinic reading.

Does a comma in 12.5 work?

Yes. 12.5 and 12,5 are read the same way.

How is mean arterial pressure calculated?

MAP is (systolic + 2 × diastolic) / 3. Age, BMI, and resting heart rate sit beside that number and do not enter the formula.

Does MAP diagnose hypertension?

No. The result is mean pressure from the two numbers you enter. Diagnosing hypertension needs readings and a clinician.

Why is diastolic counted twice?

That is the usual MAP formula: diastole lasts longer in the cycle, so it is counted twice and systole once.

Does heart rate change MAP?

No. Heart rate, age, and BMI are notes beside the result. Only systolic and diastolic change MAP.

Which units do I enter?

Pressure in mmHg, age in years, BMI in kg/m², heart rate in beats per minute. A comma in 24.5 is read the same way as a period.
