What Is This Tool?

This online converter transforms heat transfer coefficient values from Btu (th)/second/square foot/°F, an imperial unit measuring thermal energy rate per area and temperature difference, into kilocalorie (IT)/hour/square foot/°C, a unit based on international-table kilocalories and Celsius temperature differences.

How to Use This Tool?

  • Enter the value in Btu (th)/second/square foot/°F you want to convert
  • Select the source unit as Btu (th)/second/square foot/°F
  • Choose the target unit kilocalorie (IT)/hour/square foot/°C
  • Submit the input to receive the converted heat transfer coefficient value
  • Use the result for HVAC load calculations, building energy assessments, or heat exchanger evaluations

Key Features

  • Converts thermal energy transfer rates between imperial and metric-based heat transfer coefficient units
  • Supports use in HVAC design, building energy modeling, and heat exchanger analysis
  • Includes predefined conversion rate based on standardized definitions
  • Provides quick calculation with user-friendly interface
  • Useful for standardizing unit measurements across mixed unit systems

Examples

  • 2 Btu (th)/second/square foot/°F equals approximately 3263.68 kilocalorie (IT)/hour/square foot/°C
  • 0.5 Btu (th)/second/square foot/°F converts to about 815.92 kilocalorie (IT)/hour/square foot/°C

Common Use Cases

  • Estimating convective or conductive heat flux through building walls and windows using imperial units
  • Sizing heating, ventilation, and air conditioning (HVAC) equipment based on heat transfer rates
  • Calculating U-values for building elements when using imperial area units combined with kilocalorie energy units
  • Comparing convective heat transfer coefficients from experimental data reported in kcal (IT)/h·ft²·°C
  • Standardizing heat transfer coefficients for building energy modeling across different unit systems

Tips & Best Practices

  • Ensure consistent unit input to avoid calculation errors
  • Be aware of temperature scale differences between Fahrenheit and Celsius during interpretation
  • Use the conversion factor as a standard reference without adding rounding beyond tool precision
  • Apply this converter when steady-state and uniform temperature differences are assumed
  • Verify converted values when used in regulatory or critical engineering contexts

Limitations

  • Conversion assumes steady-state thermal conditions with uniform temperature differences
  • Users should consider the difference between Fahrenheit and Celsius temperature scales carefully
  • The conversion factor applies standardized kilocalorie table IT definitions; variations may affect precision
  • Transient or spatially varying temperature conditions require specialized methods beyond this conversion tool

Frequently Asked Questions

What does Btu (th)/second/square foot/°F measure?
It measures the rate of thermal energy transfer per time, area, and degree Fahrenheit temperature difference, commonly used in imperial-based HVAC and heat transfer calculations.

Why convert to kilocalorie (IT)/hour/square foot/°C?
Converting to kilocalorie (IT)/hour/square foot/°C standardizes heat transfer coefficients in international energy units and Celsius temperature scale, facilitating comparison and integration in metric-based systems.

Can I use this conversion for transient heat transfer scenarios?
No. This tool assumes steady-state and uniform temperature differences; transient or non-uniform conditions require more advanced analysis.
