| what | why it matters |
|---|---|
| The working, shown | Not just the answer - the conversion laid out. |
| Bases, units, timezones | One bench for all three, so you stop switching tools. |
| Offline | No accounts, no network, no telemetry. |
Built for the case where you need to see how the number was derived.
