How to Use This Calculator
Enter your blood pressure readings one per row — systolic (top number) on the left, diastolic (bottom number) on the right. Add as many readings as you have, then click "Calculate Average." The result shows your average BP and the AHA category it falls in.
Understanding Your Results
Systolic pressure (the top number) measures the force when your heart beats. Diastolic (the bottom number) measures pressure between beats. Both numbers matter — a reading is only "normal" if both are in range. Averaging multiple readings over several days gives a far more accurate picture than any single measurement.
