Record the reading, not an interpretation
Save the date, measured value and unit. If shoes were worn or a different instrument was used, a short note preserves that context. Avoid editing a reading simply to make a chart look smoother.
Convert units carefully
One inch is exactly 2.54 centimetres. If a tape shows feet and inches, first multiply the feet by twelve, add the remaining inches, and then convert. The unit tool below performs that arithmetic in your browser.
Keep a copy you control
The current HeightCalc journal stores measurements on your device. Browser storage can be cleared, so use its report feature or a printed blank log if you want a separate record. This guide does not add cloud backup.
