Calculate EIRP or max Tx power from gain and losses, with dBm, dBW, W, mW, ERP, and dBd to dBi conversion.

Calculate bullet kinetic energy, velocity, or weight with unit conversion, plus optional momentum, power factor, and sectional density.

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

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

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

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

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

Estimate crash impulse, momentum change, and average force with clear signs, units, rebound options, and 2-car stick-together mode.

Estimate average crash g-force from speed change plus stopping time or distance, with force, energy, and peak g estimate.
