ABSTRACT

Several different measurements of golf ball compression appear in the technical literature as each of the major golf ball manufacturers has developed its own measurement method and communicated it in its own format. However, these measurements can not be converted from one to another readily. This paper examines several measurement techniques used in the industry and correlates them to one another using a series of cores and balls formulated to give a range of stiffnesses. Correlation coefficients greater than 0.95 were obtained for correlations between Atti, Riehle, load/deflection, and Effective Modulus methods.
