| From: | To: |
The 9-hole course handicap (CH_9) represents the number of strokes a player receives for a 9-hole round on a specific golf course. It adjusts a player's handicap index to account for the difficulty of the particular 9-hole course being played.
The calculator uses the 9-hole course handicap formula:
Where:
Explanation: The formula divides the handicap index by 2 (for 9 holes instead of 18) and adjusts for course difficulty using the slope rating ratio.
Details: Accurate 9-hole course handicap calculation ensures fair competition by accounting for both player ability and course difficulty. It allows players of different skill levels to compete equitably in 9-hole matches and tournaments.
Tips: Enter your current handicap index and the 9-hole slope rating of the course you'll be playing. Slope ratings typically range from 55 to 155, with 113 being average difficulty.
Q1: What's the difference between 9-hole and 18-hole course handicap?
A: The 9-hole handicap is approximately half of the 18-hole handicap, adjusted for the specific 9-hole slope rating.
Q2: How do I find my handicap index?
A: Your handicap index is maintained through an authorized golf association or handicap service based on your scoring history.
Q3: Where can I find the slope rating for a course?
A: Slope ratings are typically posted on scorecards, course websites, or available through golf association databases.
Q4: Why is 113 used as the standard slope rating?
A: 113 represents a course of standard difficulty. The slope rating system was calibrated with 113 as the baseline average.
Q5: Can I use my 9-hole course handicap for 18-hole play?
A: No, for 18-hole play you should calculate the full 18-hole course handicap using the complete formula.
