Equivalent Pitch Speeds Conversion Chart

Related

Ever wondered how a pitch speed in one age group compares to another? How pitch speed on a youth mound compares to Major League Baseball pitch speeds?

Our handy charts below compare a given pitch speed and distance to a new distance.

So enjoy. Impress your friends.

Notes

The new "speed", of course, is not the actual speed of the given pitch, but is the equivalent speed based on the same reaction time.
These new "speeds" are not technically accurate (because of speed averages, stride length and other factors - see Reaction Time page), but they are the speeds generally mentioned on TV, and they are pretty close.
