The odds converter also calculates the breakeven win probability of a given odd, which can be very useful when evaluating a bet. For example, if you place a bet at +100 odds, then the breakeven win probability is 50%. You should only place this wager if you believe the “true” or “fair” probability of the wager winning is greater than 50%. On the other hand, if you place a bet at +900 odds, then the breakeven win probability is only 10%. You only need to win +900 wagers 1/10 times to breakeven. So if you evaluate a bet as having a 12.5% chance of winning, then this bet is mathematically profitable. The “true” odds are > 10%
