Its flight from the muzzle to the target. Just line up your current FPS with the BBs you plan to use.This 'ballistics calculator' is a computer simulation which analyzes the behavior of a round ball in To help you figure out this confusing, but essential aspect of airsoft gun quality, we’ve created this handy chart. Joules ( J) = 0.5 x the mass ( m) of the bb ( kg) x the speed squared ( v 2) To calculate kinetic energy in Joules, you must use this formula: There’s a big difference in FPS, but the kinetic energy it carries on flight will be the same, 1.52 Joules, regardless of what BB weight you use. 45g BB, your gun will be shooting 270 FPS. If your airsoft gun is shooting 400 FPS with a.

FPS is relative to the BB weight you are using but the kinetic energy it produces is always the same. If you’re customising your airsoft gun or pick up heavier BBs, you need to make sure you’re still within the limits of acceptable FPS. Check Your Gun With Our Airsoft FPS/Energy Calculator How do you work out impact? So, 1.3 joules for auto-fire or burst fire airsoft guns and 2.5 joules for single-shot or semi-auto airsoft guns. Airsoft guns, regardless of how they are powered, are not considered firearms if they are designed to fire a spherical plastic missile that is no bigger than 8mm in diameter and they have a muzzle energy that is no greater than 1.3 joules if they can fire successive shots or 2.5 joules if they can only fire individual shots. The Policing & Crime Act introduced an exception from the classification for airsoft guns as firearms, so long as they meet certain criteria. The energy expended upon firing your airsoft gun determines whether, in the eyes of the law, your airsoft gun is considered a dangerous firearm. Joules is an important measure for UK airsofters. Fully automatic airsoft guns operating at 1.3 joules or less, and single-shot (or semi automatic) airsoft guns operating at 2.5 joules or less do not engage the lethality threshold under the Firearms Act. But FPS is only half of the story when it comes to the power of your airsoft gun.Īirsoft sites differ in what is an acceptable FPS and Site Limits should always remain under the legal recommendations. The factors that determine what your FPS will include the weight of your BBs in combination with your airsoft gun power and FPS limit on your make of gun. In airsoft, you aren’t actually trying to hurt anyone, but the impact needs to be strong enough for the target to register the hit regardless of what they’re wearing. Another useful measurement for airsoft gun firing quality is the kinetic energy transferred to the target. You may find MPS on imported airsoft guns.

Countries that use the Metric System measure muzzle velocity in Metres Per Second (MPS). Heavier BBs require more energy to travel through the air, so their FPS is lower. View Below for our FPS to Joule Calculator To get the highest FPS for their airsoft guns, some players stick to the lighter BBs. A decent rate of fire can make the difference between victory and defeat, so it’s essential to know what exactly how fast you’re firing. Feet Per Second measures the muzzle velocity, or the speed your BBs travel when you fire your airsoft gun. Many airsoft players view FPS as important.
