Question 1

How is golf handicap calculated?

Accepted Answer

Under the World Handicap System (WHS), your handicap index = average of the best 8 score differentials from your last 20 rounds. Score differential = (adjusted gross score - course rating) x (113 / slope rating). Our calculator applies the WHS formula from your recent scorecards.

Question 2

How do I convert betting odds?

Accepted Answer

Decimal odds to implied probability: 1 / decimal odds x 100%. Fractional odds (e.g. 5/2) to decimal: (5/2) + 1 = 3.5. American odds: positive odds (e.g. +250) to decimal = (250/100) + 1 = 3.5. Our calculator converts between all three formats instantly.

Question 3

What is ERA in baseball?

Accepted Answer

ERA (Earned Run Average) = (earned runs allowed / innings pitched) x 9. An ERA of 3.00 means a pitcher allows 3 earned runs per 9 innings. Below 3.00 is excellent; 3.00-4.00 is above average; 4.00-5.00 is average; above 5.00 is below average.
