Since 1 US Dollar is equal to 601.5 Sudanese Pounds, we could say that n United States Dollars are equal to 601.5 times n Sudanese Pounds. In other words, we could use the following formula:
Sudanese Pounds = United States Dollars x 601.5
For example, let's say that we want to convert 2.0 United States Dollars to Sudanese Pounds. Then, we just replace United States Dollars in the abovementioned formula with 2.0:
Sudanese Pounds = 2.0 x 601.5
That is, 2.0 United States Dollars are equal to 1203.0 Sudanese Pounds.
