Heat Conduction Calculator (Fourier's Law, q=kΔT/d)

Compute 1-D steady-state heat conduction through a flat slab (Fourier's law): heat flux q = k·ΔT/d (W/m²), heat flow rate Q = k·A·ΔT/d (W), and thermal resistance R = d/(k·A) (K/W). k is the thermal conductivity (W/(m·K)); ΔT is the temperature difference (K; a °C difference equals a K difference, a °F difference is converted by ×5/9); d the slab thickness; A the cross-section area. ΔT may be negative (indicating reverse heat flow), but k, d and A must be positive. Thickness in m/cm/mm, area in m²/cm².

Quick start

Call this tool from your code in three languages.

cURL
curl -X POST 'https://api.elysiatools.com/en/api/tools/heat-conduction-calculator' \
  -H 'Content-Type: application/json' \
  -d '{"conductivity":0.04,"temperatureDiff":20,"tempUnit":"K","thickness":0.05,"thicknessUnit":"m","crossSectionArea":1,"areaUnit":"m2","decimalPlaces":4}'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Parameters

NameTypeRequiredDescription
conductivitynumberYesThermal conductivity k of the slab material in W/(m·K).
temperatureDiffnumberYesTemperature difference ΔT across the slab, in the selected Temperature Unit. May be negative to indicate the reverse heat-flow direction.
tempUnitselectNoUnit of the temperature difference. This is a difference, not an absolute temperature: Δ°C = ΔK and Δ°F ×5/9 = ΔK.
thicknessnumberYesSlab thickness d, in the selected Thickness Unit.
