Calculators

This calculator determines the required power (in milliwatts) needed to drive your headphones to a desired listening level, based on impedance, sensitivity, and desired volume.

Calculates the wheel horsepower (WHP) of a vehicle, taking into account engine horsepower and drivetrain losses.

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

This calculator determines the horsepower (HP) of an engine based on its torque and RPM.

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

Estimates the total distance required for a vehicle to stop, considering reaction time and braking distance.

Calculates the force exerted by a spring based on its spring constant and displacement.

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

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

This calculator converts a force measured in pound-force (lbf) to newtons (N).
