Currency Conversion

Converting Currency
The way that another country's money compares in value to the U.S. dollar is called the exchange rate. This rate is the factor you use to convert money amounts. For example, in England the currency is the pound (symbolized by ?). Suppose the exchange rate is 0.627 pounds for each U.S. dollar.

To change $20 to pounds, multiply 20 by 0.627 to get ?12.45.
To change ?20 to dollars, divide 20 by 0.627 to get $31.90.

Converting Measurements
Each type of measurement (length, weight, volume, etc.) has its own conversion factor from the U.S. to the metric system. Multiply or divide by the appropriate factor to convert measurements from one system to the other. For example, there are 2.54 centimeters in one inch.
To change 5 inches to centimeters, multiply by 2.54 to get 12.7.To change 5 centimeters to inches, divide by 2.54 to get 1.97.' >When doing business in another country, you have to be able to work with that country's currency and measurement systems. You often need to convert U.S. currency to foreign currency or express U.S. measurements in the metric system. To convert money amounts or measurements, you simply multiply or divide by a certain factor.
