How do I convert an exchange rate?

If you know the exchange rate, divide your current currency by the exchange rate. For example, suppose that the USD/EUR exchange rate is 0.631 and you'd like to convert 100 USD into EUR.To accomplish this, simply multiply the 100 by 0.631 and the result is the number of EUR that you will receive: 63.10 EUR.

AA is the Alpha channel, and a straight conversion would be to set AA to FF to make it full opaque:

#414141 becomes #FF414141

(Just to add: In some implementations it means the amount of Transparency where 00 means complete opaque and FF means fully transparent. In that case, #00414141 would be correct. But I think that is the exception)
