Physics

Estimate free recoil energy, recoil velocity, and impulse with US or metric units and clear SAAMI or fixed-gas methods.

Calculate SNR in dB and linear form from power, amplitude, or dB levels with clear 10 vs 20 log rules.

Convert energy, TNT mass, or explosive mass into TNT equivalent with clear units, TNT factor options, and readable outputs.

Convert watts, volts, amps, VA, and kWh for DC, single-phase, and three-phase systems with power factor and time.

Calculate psi, force, or area from force and surface area, with shape-based area helpers and optional pressure conversions.

Calculate pressure, force, or area, plus fluid depth pressure with unit conversion, gauge vs absolute results, and input checks.

Calculate reduced mass, or solve for mass 1 or mass 2, with unit handling, validation, and quick physics checks.

Convert Earth scale readings or mass into weight on planets and the Moon, with gravity values, Earth check, and optional newtons.

Calculate a car’s center of mass front-to-back, side-to-side, or height from axle and side scale measurements.

Calculate normal force on a flat surface or incline, including angled forces, contact loss, and optional friction limits.
