What it calculates
The “Biot Number” calculator computes Bi (Biot) from 3 parameters: h, w/(m²·k), l, m, k, w/(m·k).
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters h, W/(m²·K) = 100, L, m = 0.1, k, W/(m·K) = 0.6 the result is 16.67 (Bi = h·L/k).
