Calculators

Calculates frequency (cycles per second, Hz) based on period, wavelength, or wave speed.

Calculates the total volume swept by the pistons in an engine. Engine displacement is the total volume of all the cylinders in an engine, measured in cubic centimeters (cc) or liters (L).

Calculates the force exerted on a moving charge by electric and magnetic fields.

Analyzes circuits with resistors, inductors, and capacitors, calculating impedance and resonant frequency.

This calculator helps determine the appropriate shutter speeds for capturing motion or calculating long exposures based on focal length, subject speed, and desired motion blur.

Calculates how cold the air feels based on actual air temperature and wind speed.

Calculates the total equivalent capacitance of capacitors connected in parallel.

Determines the resistance and tolerance of a resistor based on its colored bands.

Calculates the electric potential (voltage) at a point due to one or more point charges or in a uniform electric field.

Calculates the difference in elapsed time between observers due to relative velocity or gravitational potential (Special/General Relativity).
