### 3/5 — Incorrect Final Density Calculations at Low Hydrometer Readings

*2025-04-26, version 1.0.6*

The app works well overall, but there’s a serious issue with the final density calculation when the hydrometer reading is below 800. For example, entering a hydrometer value of 800 with a temperature of 37.5 gives an incorrect output of 820.3, when the correct density should be 816.1. This kind of inaccuracy can lead to significant errors in real-world applications. Please fix the calculation logic to improve reliability.
