    Feet per second is one of the more cursed units of speed.

      It doesn’t line up with things mathematically, but any units of measurement when not doing a bunch of math is all simply frame of reference for whatever is easiest to understand. 30f is cold, 100f is hot, 70f feels nice.

      So I know 200fps stings (gell blasters and airsoft) 500 fps will do more than sting, a thousand fps with a lead pellet will very much go into things, and because I happen to do bench shooting of pellet rifles for distance as a hobby, I know that the speed of sound is about 1,125 fps, and if you get close to or go over that, your accuracy of a pellet rifle takes a cliff dive. My preference for my long range shots is using an extra heavy pellet in a rifle that normally would shoot around 1400 fps. It drops about 400 fps by doing so and gives the pellet enough mass to travel more steady during like a 50 yard flight, which is a lot for a little .177 diameter pellet that weighs 11 grams.
