How to use the pulse pressure calculator
Find the difference between systolic and diastolic blood pressure. Enter systolic pressure, diastolic pressure in the fields above; the pulse pressure, pulse pressure as share of systolic are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “pulse pressure”, “blood pressure difference”, “systolic minus diastolic”, “calculate pulse pressure”, “find pulse pressure”.
Formula
Variables
- sbp — Systolic pressure (mmHg)
- dbp — Diastolic pressure (mmHg)
Worked example
With systolic pressure = 120 mmHg, diastolic pressure = 80 mmHg, the calculator gives pulse pressure ≈ 40 mmHg; pulse pressure as share of systolic ≈ 33.33333 %.
Frequently asked questions
What is the pulse pressure calculator used for?
Find the difference between systolic and diastolic blood pressure. It helps with questions such as “pulse pressure”, “blood pressure difference”, “systolic minus diastolic”.
What is the formula for the pulse pressure calculation?
Pulse pressure (mmHg) = sbp-dbp. Pulse pressure as share of systolic (%) = [Pulse pressure] / sbp × 100. Here sbp is systolic pressure (mmHg), dbp is diastolic pressure (mmHg).
What inputs do I need for the pulse pressure calculator?
You need systolic pressure in mmHg, diastolic pressure in mmHg. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the pulse pressure calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the pulse pressure result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
