Calculators

Calculates velocity based on displacement and time, or using kinematic equations.

Calculates the estimated horsepower gain from adding a supercharger to a naturally aspirated engine, based on boost pressure and engine displacement.

Calculates the theoretical top speed of a boat based on its horsepower and displacement.

Calculates the force of attraction between two objects with mass using Newton's Law of Universal Gravitation.

This calculator applies Newton's Second Law (F=ma) to find force, mass, or acceleration. You can input any two values to calculate the third.

Calculates force using Newton's second law (F=ma).

Calculates the maximum vertical height reached by a projectile, given its initial velocity and launch angle.

Calculates the change in position of an object, often using kinematic equations (SUVAT).

This calculator converts between various units of force, including Newtons, dynes, pounds-force, and kilogram-force.

Converts a distance in light-years to other units of length, such as kilometers, miles, astronomical units, and parsecs.
