Working out the exchange rate on an calculator

If you think about it, it should be obvious. The "rate" is what you get of the foreign currency by spending one unit of your local currency, or what it costs a holder of the foreign currency to buy one unit of your currency.

One AUD buys USD 0.9549 according to your figures. That's around 95 cents. If something cost 100 US dollars you would need to spend more than 100 Oz dollars. You would divide the US price by the exchange rate to get the cost to you in your local currency.

100 / 0.9549 = 104.72

So if something cost USD 100 dollars you would need to spend AUD 104.72.

How about when you do not know the exchange rate used in a transaction.

The bank ATM receipt just shows how many Thai Baht given at the ATM and my American Bank shows how much in USD was debited from my account to send to the Thai Bank... The ATM receipt and the transaction screen had not information about Exchange Rate...

Example...

8050 Thai Baht (50 Baht was the Thai Bank ATM fee) Net to me was 8000 Baht --- my American Bank debited $245.28 ... plus a $2.50 ATM transaction fee - non refundable...

Rough exchange rate calculation shows.

8050 / $245.28 = 32.8196 Thai Baht per one USD

But the 50 Baht fee is included in the transaction.

Using an estimate I calculated the 50 Thai Baht equal to $1.52 ... then did ...

245.28 - 1.52 = 243.76 - then 8000 / 243.76 = 32.8191 Baht net / one USD

Does this seem reasonable when one cannot learn the exact exchange rate used in the transaction?

To calculate the exchange rate on an calculator its better for you to use a calculator rather then using a PC for calculating the exchange rate, it could be very complex for you if you did it with PC.

hmmm, what I'd exchange depends a lot on the actual calculator itself, but with out seeing it or knowing any thing about it, I'll give you 6 marbles, 2 shiny buttons and $1.20 in Canadian Tire money
