There's some confusion between Canadian and American betting markets and the primary ways that both list the odds on sporting events.

Most American-based sportsbooks use moneyline betting.  Many Canadian-based sportsbooks use decimal-based betting.  SPREADS.CA offers both options. However, the primary method is decimal listing.  Here on POINTSPREADS.CA, we go back and forth on this, occasionally using each method.

There's a site called UNDERDOG CHANCE that has a number of helpful tools for sports bettors.  They recently released a detailed video on how to convert U.S. odds to decimal, and vice-versa.  I thought it would be of interest to many readers to check out this tutorial on ways to calculate odds, using several examples.

For the math geeks out there who like to do things the old-fashioned way:

Convert decimal odds to US odds:

  • =ifs(K>2, ((K-1(*100), K<2, (-100)/(K-1), K=2,"+100")
  • K...decimal odds / example: 1.70​

Convert US odds to decimal odds:

  • =IFS(K<100,(abs(100/K))+1,K>100,(K/100)+1,K=100, 2, K=-100, 2)
  • K...US odds / example: -120
