Calculators

Calculates the engine RPM based on vehicle speed, gear ratio, final drive ratio, and tire size.

Calculates the required fuel pump flow rate based on engine horsepower and other factors.

Calculates the crosswind, headwind, and tailwind components based on wind speed and direction, and the aircraft's or vehicle's heading.

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

Estimates a car's acceleration time from 0 to 60 miles per hour based on horsepower and weight.

Calculates the power generated by hydroelectric turbines based on head, flow rate, and efficiency.

Calculates distances in Astronomical Units (AU), where 1 AU is the average distance between the Earth and the Sun.

Calculates the material removal rate (MRR) based on the volume of material removed and the machining time.

Calculates the bending stress in a beam based on applied moment, beam geometry, and material properties.

Measures or estimates the time taken to respond to a stimulus.
