Ideal Gas Law Calculator Solve the ideal gas law for P, V, n, or T with SI units. Runs locally in your browser.
Heat Transfer Calculator Compute conductive Q=kAΔT/L or convective Q=hAΔT heat transfer rate. Runs locally in your browser.
Specific Heat Capacity Calculator Solve Q = m c ΔT for heat, mass, specific heat, or temperature change. Runs locally in your browser.
Stefan–Boltzmann Calculator Compute net gray-body flux q = εσ(Th⁴−Tc⁴) and optional Q = A·q. σ from CODATA 2018. Runs locally. Not Fourier/Newton heat-transfer and not a view-factor solver.
