Calculators

Calculates the upward buoyant force exerted on an object immersed in a fluid, based on Archimedes' Principle.

Calculates the change in frequency of a wave (sound or light) due to relative motion between the source and observer.

This calculator determines the relationship between object distance, image distance, and focal length for a spherical mirror using the mirror equation.

Calculates the kinetic energy an object possesses due to its rotation (KE = 1/2 Iω²).

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

Convert between different units of capacitance.

Calculates the diffusion coefficient using the Einstein-Smoluchowski equation.

Calculates the equivalent focal length and aperture effect for cameras with sensors smaller than full-frame (35mm).

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 the amount of heat required to raise the temperature of a substance, using its specific heat capacity (Q=mcΔT).
