Calculators

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

Calculates the velocity, time, and distance of an object in free fall, neglecting air resistance.

Analyzes oscillatory motion (like a mass on a spring) calculating frequency, period, displacement, velocity, and acceleration.

Estimates the current engine horsepower of your car based on various factors.

Provides the constant speed of light in a vacuum (c) or calculates the speed of light in a medium using the index of refraction.

Calculates gravitational potential energy based on mass, gravity, and height (PE = mgh).

Calculates the index of refraction, which is the ratio of the speed of light in a vacuum to the speed of light in a medium.

Calculates the compression ratio and the resulting pressure in pounds per square inch (PSI) of an engine, given the bore, stroke, head volume, and deck clearance.

Calculates the total horizontal distance covered by a projectile before landing, considering initial velocity, launch angle, and the effect of gravity.

Calculates the local sidereal time (LST) based on Greenwich Mean Sidereal Time (GMST) and the observer's longitude.
