Arrow Ballistics Calculator

Arrow weight is in grains
Velocity in feet per second
Draw weight in pounds
Zero Distance in yards up to 40
Trajectory is inches from line of sight
All fields must be entered

Momentum units are not standard n-s
Divide by 32 for standard.

Velocity estimate assumes equal kinetic energy for each arrow weight. KE will actually increase slightly as arrow weight increases as bows are more efficient as arrow weight increases.

The KE/DW factor (kinetic energy/draw weight) is useful for comparing bows and checking your numbers. Based on published tests the approximate KE/DW factor for various designs are listed. If your KE/DW varies significantly then there is probably error in one or more of your numbers.
