Does this look up historical exchange rates for me?

No — enter both rates yourself from a source you trust (a bank statement, a rate history site, or your own records).

Is this gain taxable?

Possibly, depending on your jurisdiction and the nature of the holding — this tool calculates the currency gain or loss only, not any tax owed on it.
