Our Golf Score Equivalency Converter translates any round from Course A to an equivalent gross score on Course B by using each layout’s Course Rating and Slope. Instantly see how course difficulty impacts scoring—no spreadsheet or math degree required.

Golf Score Equivalency Converter

Convert a score from Course A to its equivalent on Course B using USGA rating & slope.

Why Compare Scores Across Courses?

No two courses play the same. A 78 on a short, wide-open parkland track may be less impressive than an 82 on a windswept championship layout. Ratings and slopes allow golfers to normalize performance, providing an apples-to-apples comparison for bragging rights, tournament seeding, or tracking personal improvement.

How the Converter Works

StepCalculationPurpose
1. Handicap DifferentialD = (Score_A − Rating_A) × 113 ÷ Slope_ANeutralizes Course A’s difficulty
2. Equivalent ScoreScore_B = D × Slope_B ÷ 113 + Rating_BApplies the same performance to Course B’s difficulty

Legend

  • Score_A – Your gross score on Course A
  • Rating_A, Slope_A – Course A’s published values
  • Rating_B, Slope_B – Course B’s published values
  • D – Handicap differential (lower is better)

Step-by-Step Instructions

  1. Enter your score on Course A – Use your actual 18-hole gross.
  2. Add Course A’s Rating & Slope – Found on the scorecard or USGA database.
  3. Add Course B’s Rating & Slope – The track you want to benchmark against.
  4. Read the results:
    • Equivalent Score shows what that round would look like on Course B.
    • Handicap Differential is useful for tracking index updates.
  5. (Optional) Hit Reset to clear the form.

Practical Example

Scenario

  • Score on Course A: 82
  • Course A Rating/Slope: 71.2 / 128
  • Course B Rating/Slope: 74.6 / 142

Results

  • Handicap Differential: (82 − 71.2) × 113 ÷ 128 ≈ 9.5
  • Equivalent Score on Course B: 9.5 × 142 ÷ 113 + 74.6 ≈ 86.5

Tips for Real-World Use

  • Plan tournaments – Estimate what scores will be competitive on unfamiliar courses.
  • Evaluate progress – Compare early-season rounds at an easy track to late-season rounds at a tougher one without bias.
  • Set fair bets – Level the playing field when friends play different home courses.
  • Know your index impact – The differential output mirrors what the USGA uses for handicap updates.

Limitations

  • Assumes scores are 18-hole, gross. For nine-hole or net scores, results will be off.
  • Ignores pace-of-play, weather, and course setup (tees, pin positions).
  • Uses USGA formulas; other federations may vary slightly.
