Conversor de Condutividade Térmica — Formula

How to Convert Thermal Conductivity Units

Formula

BTU/(hr·ft·°F) = W/(m·K) x 0.5778

Thermal conductivity describes how well a material conducts heat. The SI unit is Watts per meter-Kelvin. The imperial unit is BTU per hour-foot-degree Fahrenheit. The conversion factor of 0.5778 combines the energy conversion (W to BTU/hr), length conversion (m to ft), and temperature conversion (K to °F interval).

Exemplo Resolvido

Convert 1 W/(m·K) to BTU/(hr·ft·°F).

  1. Apply the conversion factor: 1 W/(m·K) = 0.5778 BTU/(hr·ft·°F)
  2. BTU/(hr·ft·°F) = 1 * 0.5778 = 0.5778
  3. Also: 1 W/(m·K) = 0.002388 cal/(s·cm·°C)
