Heat Transfer Coefficient Calculator

Calculate convection coefficient (h), overall heat transfer coefficient (U-value), and heat flow using measured data, series resistances, or LMTD heat exchanger method.

Convection h U-Value Thermal Resistance LMTD

Heat Transfer Coefficient, U-Value & Heat Flow Estimator

Compute h from q, A, and ΔT; compute U from layer resistances; or use LMTD for heat exchanger estimation. Includes unit conversion and CSV export.

Layer Thickness k (Conductivity) R = L/k
