I had to change sportsbooks today, and am used to working with decminal lines like 2.90 or 1.90. Anyways, now with my new book (BoDog), they only have the (-175) or +155 lines....

How do I convert a -175 into a decimal format ?

Thanks for the help!

1.57

100/175 + 1

Also, if you're not accustomed to American style moneylines, keep this chart handy for reference:

Thanks for the info!

To do a +155, I would do this:
155/100 +1 = 2.55

Is that correct as well ?

You are correct, sir.
