Science Calculators
6Science and engineering calculators for physics, electricity and mechanics: Ohm's law, speed, distance, time, force and mass. Free and instant.
Ohm's Law CalculatorCalculate voltage, current, resistance or power using Ohm's law (V = IR). Enter any two values to find the remaining electrical quantities.Speed CalculatorCalculate speed, distance or time using the formula speed = distance / time. Results shown in m/s, km/h and mph simultaneously.Force CalculatorCalculate force, mass or acceleration using Newton's second law F = ma. Also shows weight in Newtons for the given mass.Density CalculatorCalculate density, mass or volume using the density formula (density = mass / volume). Enter any two values to find the third.Molarity CalculatorCalculate the molarity of a solution from the mass of solute, its molar mass, and the solution volume. Instant, accurate result.Wind Chill / Heat Index CalculatorCalculate wind chill in cold, windy weather or heat index in hot, humid weather, using the official US National Weather Service formulas.
