Energy, work, and power Calculators
In Physics
Bullet Energy Calculator
Find out how much energy a bullet fired from a weapon carries using this bullet energy calculator.
EIRP Calculator — Effective Isotropic Radiated Power
The EIRP calculator helps you determine the effective isotropic radiated power, i.e., the actual power level radiated from an antenna.
Elastic Potential Energy Calculator
Use the elastic potential energy calculator to determine the potential energy of a spring.
FPE calculator — Foot-pounds of Energy
Quickly calculate the foot-pounds of energy with our FPE calculator. You only need to know the weight and the velocity of your projectile.
Impact Energy Calculator
Calculate the force and energy involved with impact loads using our impact energy calculator.
Kinetic Energy Calculator
If you know the mass and velocity of an object, use the kinetic energy calculator to find its energy in movement.
Potential Energy Calculator
Grab the potential energy calculator to find how much energy is stored in an object raised off the ground.
Power-to-Weight Ratio Calculator
Our power-to-weight ratio calculator allows you to compare the performance of different motor vehicles.
Quiz: Potential Energy Calculator
Take a quiz to check your understanding of gravitational potential energy in physics.
Recoil Energy Calculator
Calculate the recoil of firearms using the recoil energy calculator.
Signal-to-Noise Ratio Calculator
The SNR (signal-to-noise ratio) calculator computes the ratio of the desired signal to the level of background noise.
TNT Equivalent Calculator
Use the TNT equivalent calculator to determine the TNT factor and compare different explosives.
Watt Converter
Convert watts, kilowatts, horsepower, BTU per hour, foot-pounds per second and tons of refrigeration. A watt is a rate of energy use, not an amount.
Work and Power Calculator
Our work and power calculator can determine how much energy you need to perform a given amount of work.
Work Calculator
Do you want to calculate work (physics) with very little effort? With Omni's work calculator we'll do the (computational) work for you 😉
