Currency exchange rate
Aha! I have found a currency page that is actually functioning!
Rates @ 03/08/2020 on-line for the equivalent of £100.
These are a guide only, you may find better/worse deals elsewhere.
But never, NEVER change money at the airport. You are a captive audience and will be ripped off!
£1 GBP = €1.08 (Euro) and 8.07 Kuna (Croatia).
Other currencies are available (obviously) but these are the only I have used since the Euro was introduced.
