i agree with that it is 1.68, and the british ball is 1.62, did you know that the average weight of a Golf ball is 1.62 ounces, or 43.93 grams
A minimum of 1.68 inches. The old British 1.62 inch standard became obsolete in 1990.
I don't have the exact dimensions but I looked this up a few weeks ago. The Diameter is approx 1.60 inch which means the radius is about 0.80 inch.
Under the rules of golf, the maximum or minimum circumference of a golf ball is not mentioned. However, a golf ball has a circumference of 5.275 inches.
No less than 1.68 inches.
The density of golfball is less then density of water
