Physics & Engineering Calculators (34)

This collection covers the real math behind classic physics and electronics. Reach for an ohms law calculator when you need voltage, current, or resistance solved instantly, or work through electrical power, capacitors and resistors, kinetic and potential energy, force, mass, and acceleration, projectile motion, frequency and wavelength, fluid flow rate, and buoyancy under Archimedes' principle. There is also an LED resistor calculator, an antenna length calculator, and battery life and charge time estimators for real electronics projects.

The automotive and mechanical side gets just as much depth. A tire size calculator tells you exactly what fits before you buy, and once the wheels are on, a wheel offset calculator checks real fender clearance. From there, work out gear ratio and RPM to MPH conversions, compression ratio and compression ratio to PSI, boost and wheel horsepower, a 0-60 time estimate, and a quarter mile horsepower method for engine builds. Round it out with turbo sizing, gas oil ratio for two stroke engines, GVWR, winch size, speedometer gear, crosswind and windsock readings for pilots, traffic density, and a boat speed calculator for anyone on the water.
