Energy Work And Power calculators
12 calculators Elastic Potential Energy Calculator Solve the spring energy formula U = ½·k·x² for energy, spring constant, or displacement. Switch units, see the restoring force, and find the launch speed of a mass.
Open Kinetic Energy Calculator Find kinetic energy from mass and speed, or solve in reverse for mass or velocity. Switch mass, speed and energy units, see momentum and energy conversions.
Open Potential Energy Calculator Find gravitational potential energy from mass, height and g, or reverse solve for any one. Planet gravity presets, metric and imperial units, plus energy equivalents.
Open Work Calculator Calculate work (W = F·d·cosθ) in joules, or reverse-solve for force, distance, or angle. Add a time for power in watts, switch N/lbf/ft/m units, or use velocity change.
Open Bullet Energy Calculator Calculate bullet kinetic energy in foot-pounds and joules. Includes hunting suitability guide, cartridge reference table, and metric/imperial unit switching.
Open Impact Energy Calculator Calculate impact energy from mass and velocity, drop height, or a Charpy/Izod pendulum test. Metric and imperial units, impact force, and real-world examples.
Open Power-to-Weight Ratio Calculator Calculate power-to-weight ratio in W/kg, kW/tonne, hp/lb and more. Works for cars, cycling and any engine. See your vehicle or fitness category instantly.
Open Recoil Energy Calculator Calculate firearm free recoil energy (ft-lbf or joules), recoil impulse, and recoil velocity. Enter bullet weight, muzzle velocity, powder charge, and gun weight.
Open Signal-to-Noise Ratio Calculator Calculate signal-to-noise ratio (SNR) in decibels using power, voltage, simple ratio, dB difference, or coefficient of variation. Instant results with worked steps.
Open TNT Equivalent Calculator Convert energy to TNT equivalent mass instantly. Choose from 14 explosives or enter custom values. Includes blast overpressure, damage zones, and worked steps.
Open Watt Converter Convert watts to kilowatts, horsepower, BTU/h, megawatts, dBm and 15 other power units instantly. Shows the formula, worked example, and a full comparison table.
