How to Calculate Golf Club Swing Speed
While there are various electronic tools which can be used to measure the club-head speed of a golf swing at the moment of impact, they are often too costly for the everyday golfer. A more affordable method of testing the hand-speed or club-head speed of your golf swing can be replicated with a common camcorder and a calculator.

1
Line up the camera so that it will record a side view of your golf swing, with the ball between you and the camera. Start recording.
-
2
Record yourself hitting the ball. Recording multiple swings will allow you to get more accurate data.

3
Play back your swing. Using your camera's frame-by-frame function, count the number of frames it takes for your swing to progress from the point where your arms are parallel to the ground to the point where you impact the ball (your "swing frame rate"). If you recorded multiple swings, measure a "swing frame rate" for each swing and calculate an average.
-
4
Divide the "swing frame rate" by your camera's frames-per-second rate. This will give you the time, in seconds, that it takes for you to complete that portion of your swing.
-
5
Measure the distance from the center of your chest, between your shoulders, to the head of the golf club, in inches.
-
6
Multiply this number by 1.57 to determine the distance in inches your club head travels in the measured time.
-
7
Divide this number by the time found in Step 4 to determine how many inches your club traveled per second.
-
8
Multiply this number by 3600 (the number of seconds in an hour) to determine how many inches per hour your club traveled.
-
9
Divide this number by 12 to determine how many feet per hour it is traveling, as there are twelve inches in a foot.
-
10
Divide this number by 5,280 to convert your data to miles per hour, as there are 5,280 feet in a mile.
