Line Converter Calculator
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.
