Thermal Conductivity Rechner — Formel
## Thermal Conductivity (Fourier's Law)
Fourier's law describes the rate of heat conduction through a material.
### Formula
**Q/t = k * A * DeltaT / d**
where k is thermal conductivity, A is area, DeltaT is temperature difference, and d is thickness. Lower k means better insulation.

Lösungsbeispiel
Heat loss through a 10 m² wall, 10 cm fiberglass insulation (k=0.04), 20°C temperature difference.
- Q/t = k * A * DeltaT / d
- Q/t = 0.04 * 10 * 20 / 0.1
- Q/t = 8 / 0.1
- Q/t = 80 W
