Example 1: A male 50-yard freestyle time of 23.78 is multiplied by 1.119 to yield a 50-meter time of 26.61 (26.6098 rounded to the nearest 0.01).
Example 2: A female 400-meter freestyle time of 4:27.47 is changed to seconds (4 X 60 sec/min + 27.47 = 267.47 sec) and multiplied by 1.140 to yield a 500-yard time of 304.92sec, which converts to 5:04.92.(304.9158 is rounded to 304.92 and that number is converted to minutes and seconds.)
