Browse calculators0-60 Acceleration Calculator The 0-60 calculator works out the average acceleration of a vehicle that goes from a standstill to a chosen speed in a given time. Enter the 0-60 time (in seconds) and the speed reached (in mph) and you get the average acceler — free online calculator.
Angular Velocity Calculator The Angular Velocity Calculator converts a rotational speed in RPM into angular velocity, then uses the radius to find tangential speed and centripetal acceleration. The formula used is: ω = RPM × 2π/60; v = ω × r; a_c = ω² × r — free online calculator.
Compression Ratio Calculator The Compression Ratio Calculator finds an engine's compression ratio from the cylinder (swept) volume and the clearance (combustion chamber) volume. — free online calculator.
Compression Ratio to PSI Calculator The Compression Ratio to PSI Calculator estimates an engine's cranking compression pressure from its compression ratio using a polytropic approximation. Enter the compression ratio. — free online calculator.

Heat Energy Calculator (Q = mcΔT) Calculate the heat energy needed to change a substance's temperature. Enter the mass, the material's specific heat capacity, and the temperature change, and this calculator applies Q = mcΔT to give the energy in joules. — free online calculator.
Moment of Inertia Calculate moment of inertia (rotational resistance). Formula: I = Σ(m_i × r_i²). For uniform disk: I = 0.5MR²; uniform rod: I = (1/12)ML² — free online calculator.
Radioactive Half-Life Calculator Calculate remaining mass after N half-lives. Mass = Initial × (0.5)^N. — free online calculator.
