Use our ECG Boxes to Seconds Calculator to effortlessly convert the number of small or large boxes on an electrocardiogram into precise time durations. Ideal for students and professionals to quickly determine ECG intervals like PR, QRS, and QT, aiding in accurate EKG interpretation.
Formula:
The ECG Boxes to Seconds Calculator uses the following simple formulas:
- For Small Boxes: Time (seconds) = Number of Small Boxes × 0.04
- For Large Boxes: Time (seconds) = Number of Large Boxes × 0.20
- Number of Boxes: The count of small or large boxes observed on the ECG paper.
- 0.04: The duration in seconds represented by one small ECG box.
- 0.20: The duration in seconds represented by one large ECG box (5 small boxes).
