# Line Converter Calculator

#### Instructions

The Line Converter Calculator can convert American betting lines (aka moneylines) to percentages and vice versa.

If you are converting a **line to a percentage**, type in the line (include a “-”/negative sign if the line is a favorite) to the American Line box, and then click the **Calculate Percentage button**.

If you are converting a **percentage into an American betting line**, type in the percentage number (without the “%” sign) into the Percentage to Win box, and then click the **Calculate American Line button**.
