Heat transfer occurs via conduction, convection and radiation. Calculate the first two here.
Conduction: Q = kA·ΔT/L (Fourier's Law). Convection: Q = hA·ΔT (Newton's Law of Cooling).
Reach for this calculator when a quick, verified engineering computation is needed without opening specialised software. The formula used follows the relevant standard and is documented for reference.
A frequent mistake is using nominal or rated values when actual measured values are required. Calculations based on nominal dimensions or catalogue specifications may not match field conditions — always use measured values where precision matters.
A mechanical engineer verifies a beam's deflection under a specified load using standard formulas. Running the calculation with exact dimensions confirms the design meets deflection limits before fabrication — catching an issue that would be expensive to correct in the field.
Conduction: heat through solid material. Convection: heat transfer via fluid (air/liquid) movement.
