Still confused on what FPS (feet per second) is all about? Here is Tang of Fox Airsoft to explain this term that airsoft players talk about all the time... and there is Joules which is discussed in many groups. But for now, it's about FPS... "Hello newbie airsofters! Today I want to touch on the subject of airsoft gun velocity. This will help you understand how to measure your airsoft gun's performance and know objectively how hard a gun shoots. It is important to know this before buying or upgrading your guns because fields have limits on how hard your guns can shoot.

*FPS is a unit of measurement for velocity but does not necessarily translate properly how hard an airsoft gun shoots (and how much it hurts). Joules is a measure of energy and is a more useful unit of measurement to determine this."
