What Is This Tool?

This tool converts heat transfer coefficient values from kilocalorie (IT) per hour per square foot per degree Celsius to Btu (thermal) per second per square foot per degree Fahrenheit. It helps translate thermal performance data between metric-based and imperial-based units frequently encountered in HVAC engineering and building analysis.

How to Use This Tool?

  • Enter the heat transfer coefficient value in kilocalorie (IT)/hour/square foot/°C.
  • Select the source unit (kilocalorie (IT)/hour/square foot/°C) and target unit (Btu (th)/second/square foot/°F).
  • Apply the conversion to obtain the equivalent value in Btu (th)/second/square foot/°F.
  • Use the converted value for HVAC design, energy calculations, or heat exchanger assessments.

Key Features

  • Converts heat transfer coefficients using established unit definitions.
  • Supports imperial and metric unit conversions essential in HVAC and energy auditing.
  • Provides clear multiplication formulas reflecting conversion rates between units.
  • Facilitates compatibility with equipment specs and thermal performance data.

Examples

  • 5 Kilocalorie (IT)/hour/square foot/°C equals 0.003064025 Btu (th)/second/square foot/°F.
  • 10 Kilocalorie (IT)/hour/square foot/°C converts to 0.00612805 Btu (th)/second/square foot/°F.

Common Use Cases

  • Defining overall heat transfer coefficients (U-values) for building components in imperial units.
  • Sizing and selecting HVAC equipment based on thermal performance data in kcal/h·ft²·°C or Btu/th·s·ft²·°F.
  • Comparing convective heat transfer coefficients from experiments or energy audits with differing unit systems.
  • Assessing surface heat fluxes of heat exchangers and cooling/heating surfaces using imperial measurements.

Tips & Best Practices

  • Ensure consistency in temperature and time units when applying conversions to maintain accuracy.
  • Use steady state heat transfer assumptions when interpreting converted values.
  • Confirm unit selection matches the measurement context to avoid errors in HVAC calculations.

Limitations

  • Conversion involves different temperature scales (°C vs °F) and time units (hour vs second), requiring careful attention.
  • Assumes steady state heat transfer; does not consider transient conditions or material variability.
  • Does not provide direct conversion formulas beyond the given rate; context-specific factors may affect results.

Frequently Asked Questions

Why is this conversion important in HVAC applications?
It aligns heat transfer data with the imperial units commonly used in HVAC design, enabling compatibility with equipment specifications and performance metrics.

What units are involved in this conversion?
