Corrections and updates

The UK doesn't use dollars and never has. They use pounds sterling and have done so for about a millennium.

The above rate was correct at the time the question was answered, but exchange rates change almost every day so any conversion factor posted here would be out of date within 24 hours. For the latest rates you can check sites such as www.xe.com or CNNMoney.
