What is the circumference of a golf ball?
The United States Golf Association specifies that a golf ball must weigh no more than 1.620 ounces, be spherical in shape and be no less than 1.68-inches in diameter. This is called “The American Ball”. The “British Ball” is a teensy bit smaller, at 1.62-inches. That may seem like too tiny a difference to mean anything tangible. But that 3.7% difference in diameter translates into 7.5% less wind that the ball must cut through during flight. You know those mail-order balls with the secret name, guaranteed to add 20 yards to your drive? Those are British Balls, which are illegal for use in play sanctioned by The USGA and now even in tournaments of The Royal and Ancient Club. Source(s): http://www.leaderboard.com/glossary_ball…
