## How conversion works

All 20 currencies are stored as rates relative to USD. The conversion formula is:

```
converted = amount × (rate_to / rate_from)
```

For example, to convert €100 to Japanese Yen:
- EUR rate vs USD = 0.92 → 1 EUR = 1/0.92 USD
- JPY rate vs USD = 149.5 → 1 USD = 149.5 JPY
- €100 = 100 × (149.5 / 0.92) ≈ 16,250 JPY
