Calculators

Estimates calories burned specifically while swimming, based on duration, stroke, and weight.

Calculates the shortening of an object's length as measured by an observer moving relative to it (Special Relativity).

Calculates the minimum speed needed for an object to escape the gravitational influence of a celestial body.

Calculates how much time you spend on TikTok and suggests alternative activities.

Calculates the degrees of freedom (F) in a system using Gibbs' Phase Rule: F = C - P + 2, where C is the number of components and P is the number of phases.

Calculates the finished and cut sizes for half-square triangles (HSTs) used in quilting.

Calculates the lattice energy of an ionic compound using a simplified Born-Landé equation. This calculator provides an estimate of the energy required to separate one mole of a solid ionic compound into gaseous ions.

Calculates the cosine of an angle (given in degrees or radians).

Estimates the load requirements of your generator to ensure it can handle the appliances you need to power.

Calculates the kinetic energy of an object based on its mass and velocity.
