Calculators

Combines calculations for both work done and the rate at which it is done (power).

Calculates the energy equivalent of mass (or vice-versa) using Einstein's famous equation.

Calculates the percentage of time a signal or system is active within a given period.

Calculates the radius of the event horizon for a non-rotating black hole of a given mass.

Calculates stress as force applied per unit area within a material (σ = F/A).

Calculates the rotational equivalent of force, causing an object to rotate (τ = rF sin θ).

Converts distances between light-years and other units, such as kilometers, miles, astronomical units, and parsecs.

Calculates the orbital period or semi-major axis of an orbiting body using Kepler's Third Law.

Calculates power as the rate at which work is done or energy is transferred. You can calculate power using work and time (P = W/t) or force and velocity (P = Fv).

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