Calculation path

Calculate steady one-dimensional conduction rate through a uniform slab. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

What you provide

What you provide

  • Thermal conductivity expressed in W/(m K), using the same scenario as the other inputs
  • Conduction area expressed in m^2, using the same scenario as the other inputs
  • Temperature difference expressed in K, using the same scenario as the other inputs
  • Material thickness expressed in m, using the same scenario as the other inputs

What you receive

What you receive

  • Heat-transfer rate in W from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Heat flow is steady and one-dimensional with constant conductivity and no contact resistance.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
