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 acceleration based on change in velocity and time, or using force and mass (F=ma).

Converts Newton meters (Nm), a unit of torque, to other torque measurement units.

Calculates the diffusion coefficient using the Einstein-Smoluchowski equation.

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

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

Calculates pressure as force applied per unit area (P = F/A).

Calculates the total time a projectile spends in the air, considering initial velocity and launch angle.

Calculates traffic density based on flow and speed.

Calculates speed, distance, or time based on the other two values.
