How Do Chronographs Work
Basically, chronographs measure the time it takes for a pellet fired from a gun to pass between two sensors. To work out the energy output, which is calculated as feet per second (fps). The reading has to be multiplied by itself, then multiplied by the weight in grains of the pellet and divided by 450,240.
