Calculators

Calculates the air-fuel ratio (AFR), which represents the mass ratio of air to fuel in an internal combustion engine. This ratio is crucial for efficient combustion and emissions control.

Calculates the heat absorbed or released during a phase change (melting, boiling) at constant temperature (Q=mL).

Calculates the difference in elapsed time between observers due to relative velocity or gravitational potential (Special/General Relativity).

Calculates the Reynolds number, a dimensionless quantity that helps predict fluid flow patterns (laminar vs. turbulent).

Calculates density as mass per unit volume (ρ = m/V).

Calculates the kinetic energy an object possesses due to its rotation (KE = 1/2 Iω²).

Calculates frequency (cycles per second, Hz) based on period, wavelength, or wave speed.

Calculates the rate of change of angular position (how fast an object rotates or revolves).

Calculates the force of static or kinetic friction based on the normal force and coefficient of friction.

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