Calculators

Calculates the change in velocity (delta-v) a rocket can achieve based on propellant mass and exhaust velocity.

Calculates the Young's Modulus of a material, which represents its stiffness. This is the ratio of tensile stress to tensile strain.

Calculates the heat absorbed or released during a phase change (melting, boiling) at constant temperature (Q=mL).

Calculates the magnetic field strength at a distance from a long, straight wire carrying current.

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

Calculates the angle of refraction of light as it passes from one medium to another, using Snell's Law. This law describes how light bends when it transitions between two different substances with varying indices of refraction.

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).

Estimates the distance to galaxies based on their redshift (recessional velocity) using Hubble's constant.

Calculates the speed at which an object orbits around another body, based on the mass of the central body and the orbital radius.

Calculates the volume or mass of fluid passing a point per unit time.
