Kinetic Energy Calculator
The chart is a close approximation of arrow speed calculated by inches of arrow drop between 20 & 40 and 20 & 60 yards.
You must be able to shoot a "decent group" at 40 and/or 60 yards.This method is better than nothing if you do not have access to a chronograph. All numbers are rounded to the nearest inch.
