Describe the bug
Converter doesn't keep inputs after clicking the "Update rates" button.

Steps To Reproduce

1. Launch the calculator
2. Open the currency converter
3. Select currency pair and enter any value for base unit.
4. Click on "Update rates"

Expected behavior
It would be nice if the converter keeps the inputs when you click the "Update rates" button or recalculate result automatically (based on from unit) if ratio have changed. This will prevent re-entering the same amount again.
