What it calculates
The “Thermal Conductivity (k)” calculator computes k (conductivity) in W/(m·K) from 4 parameters: heat flux q, w, thickness l, m, a, m², δt, k.
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Heat flux Q, W = 100, Thickness L, m = 0.1, A, m² = 1, ΔT, K = 20 the result is 0.5 W/(m·K) (k = Q·L / (A·ΔT)).
How to use
