Here you’ll find two handy tools that airsoft players can use to ensure that their guns are shooting within safe limits and comply with field regulations.
The airsoft FPS calculator allows you to calculate the velocity of your gun by measuring the distance a BB travels in feet and the time it takes to travel that distance in seconds.
The airsoft kinetic energy calculator lets you determine the kinetic energy of a BB in joules, by entering the weight of the BB in grams and its velocity in FPS.
Both of these calculators are important tools for airsoft players who want to ensure the safety of themselves and others while playing airsoft.
Airsoft FPS Calculator
The calculator works by entering the distance the BB travels in feet and the time it takes to travel that distance in seconds. Using this information, the calculator can determine the FPS of the gun.
It is important to note that different fields may have different rules regarding the maximum allowable FPS for airsoft guns, so be sure to check the regulations of the specific field or event you plan to attend.

Airsoft Kinetic Energy (Joules) Calculator
In airsoft, KE is calculated using the weight of the BB and its velocity, measured in feet per second (FPS).
This joules calculator uses the formula J = 0.5 x m x v^2, where m is the mass of the BB in grams, and v is the velocity of the BB in meters per second (m/s).
This information is useful for airsoft players to ensure that their guns are shooting within safe limits and to comply with field regulations.

What is The Current Airsoft Power Limit in the US?
Generally, the average allowable FPS for airsoft guns in the US ranges from 350 FPS to 500 FPS, with most fields capping at around 400 FPS for automatic electric guns (AEGs) and 500 FPS for bolt-action sniper rifles.
It is important to note that these limits can change depending on the type of gun and BB weight used, so it is always best to check the regulations of the specific field or event you plan to attend.
Average FPS of Airsoft Guns by Type
Spring-Powered Airsoft Guns:
- Bolt-action sniper rifles: 400 to 550 FPS
- Spring-powered pistols: 200 to 300 FPS
Electric-Powered (AEG) Airsoft Guns:
- Entry-level AEGs (e.g., SMGs): 300 to 350 FPS
- Standard AEGs (e.g., rifles): 350 to 400 FPS
- High-powered AEGs (e.g., designated marksman rifles): 400 to 450 FPS
Gas-Powered Airsoft Guns:
- Gas blowback pistols: 300 to 350 FPS
- Gas blowback rifles: 350 to 450 FPS
It’s important to note that these are general guidelines, and specific field rules or event regulations may have different FPS limits. Additionally, some airsoft guns may have adjustable FPS settings, allowing players to modify their guns within certain limits. Always adhere to local regulations and guidelines to ensure a safe and enjoyable airsoft experience.
FAQ
FPS stands for “feet per second” in airsoft. It is a measure of the speed at which the BB leaves the barrel of an airsoft gun. FPS is an important factor in airsoft as it determines the kinetic energy of the BB, which is a measure of the energy an object possesses due to its motion.
To calculate FPS (feet per second) of an airsoft gun, you’ll need to measure the distance a BB travels in feet and the time it takes to travel that distance in seconds. Once you have these measurements, you can use the following formula: FPS = (Distance in feet) / (Time in seconds).
The kinetic energy of airsoft guns is the energy that is transferred to the BB when it is fired from the gun. Kinetic energy is a measure of the energy an object possesses due to its motion.
In airsoft, the kinetic energy of the BB is determined by its weight and velocity, which is usually measured in feet per second (FPS) or meters per second (m/s). The formula to calculate the kinetic energy of an airsoft BB is KE = 0.5 x m x v^2, where m is the mass of the BB in grams and v is the velocity of the BB in meters per second.
The weight of a BB used in airsoft can vary depending on the manufacturer and the intended use of the BB. Generally, airsoft BBs range in weight from 0.12 grams to 0.48 grams, with 0.20 gram BBs being the most commonly used for standard gameplay.
The ideal FPS for airsoft guns varies depending on the type of gameplay and the specific field rules. In general, FPS limits for most airsoft fields range from 300 FPS to 400 FPS for AEGs (Automatic Electric Guns) and gas-powered guns, and 450 FPS to 550 FPS for sniper rifles. It’s important to check the field rules and regulations before playing and to ensure that your airsoft gun meets the FPS limits set by the field.
