Merwins EPV Calculator 16

Merwin’s EPV Calculator is a tool designed to determine the volume of a spherical cap based on a cross-section through its middle. Utilizing a complex polynomial equation, the calculator incorporates measurements of width, height, and thickness of the cross-section to provide accurate results.

For practical illustration, normative curves displaying percentile lines at the 10th, 50th, and 90th percentiles are generated alongside derived percentiles. These visuals serve as examples of real-world applications. The data in the presented sample is recorded in centimeters for lengths and weeks and days for time.

• Input sample name and time in weeks and days
• Easily input dimensions of width, height, and thickness
• Instant calculation of spherical cap volume through mathematical modeling
• Immediate visualization of volume on a normative curve, distinguishing normal (green) from alert values (red)
• Ability to view results and curves in landscape mode for better visualization
• Effortless sharing of results using Apple’s standard share feature
• Convenient updating, recalculation, or clearing of data for new samples
• Calculation of placenta weight percentile post-delivery and birth weight to placenta weight ratio if birth weight is known
