I've completed the first tranche of tools. There are converters and calculators.
Calculators
- Calculate compound interest
- Calculate a target temperature unit from a source one. (Perhaps this should be in converters?)
Converters
Converters contain a couple of useful ones:
- Convert plain text into base64 encoded text and vice versa.
- Convert plain text into url encoded text and vice versa. Allows double-encoding/double-unencoding.
