Understanding the formulas used for conversion is essential for accuracy. The tool includes detailed explanations of the formulas utilized, allowing users to verify results and comprehend the underlying calculations. Below are the key formulas for the Heat Transfer Coefficient Converter:

  • Watts per Square Meter Kelvin (W/m²·K) to British Thermal Units per Hour per Square Foot Fahrenheit (BTU/hr·ft²·°F): BTU/hr·ft²·°F = W/m²·K × 0.5778

    Example Calculation: If the heat transfer coefficient is 100 W/m²·K:

    BTU/hr·ft²·°F = 100 × 0.5778 ≈ 57.78 BTU/hr·ft²·°F
  • British Thermal Units per Hour per Square Foot Fahrenheit (BTU/hr·ft²·°F) to Watts per Square Meter Kelvin (W/m²·K): W/m²·K = BTU/hr·ft²·°F × 1.732

    Example Calculation: If the heat transfer coefficient is 50 BTU/hr·ft²·°F:

    W/m²·K = 50 × 1.732 ≈ 86.6 W/m²·K
  • Calories per Second per Square Centimeter Celsius (cal/s·cm²·°C) to Watts per Square Meter Kelvin (W/m²·K): W/m²·K = cal/s·cm²·°C × 41.84

    Example Calculation: If the heat transfer coefficient is 0.02 cal/s·cm²·°C:

    W/m²·K = 0.02 × 41.84 ≈ 0.8368 W/m²·K
  • Watts per Square Meter Kelvin (W/m²·K) to Calories per Second per Square Centimeter Celsius (cal/s·cm²·°C): cal/s·cm²·°C = W/m²·K × 0.0239

    Example Calculation: If the heat transfer coefficient is 500 W/m²·K:

    cal/s·cm²·°C = 500 × 0.0239 ≈ 11.95 cal/s·cm²·°C
