Preview Conduction Through a Uniform Material Calculator

Q = -k · A · (T_{2} -T_{1}) / L

where

Q = rate of heat transfer (W or Btu/hr)

A = wall surface area normal to heat flow (m^{2} or ft^{2})

L = wall thickness (m or ft)

T_{1} = temperature of one surface of the wall (K or °F)

T_{2} = temperature of the other surface of the wall (K or °F)

k = thermal conductivity (Btu / (hr-ft-°F)
