What Is This Tool?

This converter is designed to translate thermal conductivity measurements from Btu (th) inch/hour/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F. These units quantify heat flow through materials in U.S. customary engineering measurements, aiding in building energy modeling and HVAC system design.

How to Use This Tool?

  • Enter the value in Btu (th) inch/hour/sq. foot/°F you wish to convert.
  • Select the source unit as Btu (th) inch/hour/sq. foot/°F.
  • Choose the target unit as Btu (th) foot/hour/sq. foot/°F.
  • Click the convert button to obtain the equivalent value in the target unit.

Key Features

  • Converts thermal conductivity units using a straightforward conversion rate.
  • Supports units commonly used in insulation and building material analysis.
  • Helps translate inch-based conductivity values to foot-based values for consistency.
  • Facilitates compatibility with building codes and engineering calculations.

Examples

  • 12 Btu (th) inch/hour/sq. foot/°F converts to 1 Btu (th) foot/hour/sq. foot/°F.
  • 6 Btu (th) inch/hour/sq. foot/°F converts to 0.5 Btu (th) foot/hour/sq. foot/°F.

Common Use Cases

  • Specifying thermal conductivity (k-value) of insulation boards and foam materials.
  • Calculating heat loss or gain through building envelopes for energy modeling and HVAC sizing.
  • Converting between inch- and foot-based thermal conductivity measurements for compliance with building standards.
  • Engineering conduction heat transfer assessments using U.S. customary units.

Tips & Best Practices

  • Ensure consistent units throughout your calculations for accuracy.
  • Use exact values rather than rounded numbers when precise engineering data is required.
  • Be aware of material uniformity and temperature gradient assumptions in your applications.
  • Double-check conversion inputs to avoid errors in heat transfer estimations.

Limitations

  • Conversion assumes uniform material thickness and constant temperature gradients, which may not hold true for heterogeneous materials.
  • Rounding during conversion can affect precision; detailed engineering should use exact values and consistent unit standards.

Frequently Asked Questions

What does Btu (th) inch/hour/sq. foot/°F measure?
It measures the heat flow in British thermal units transmitted per hour through a material one inch thick with one square foot area, for a one degree Fahrenheit temperature difference.

Why convert Btu (th) inch/hour/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F?
Converting allows compatibility with thermal conductivity values expressed for materials measured in feet thickness, facilitating building energy calculations and adherence to imperial standards.

Can the conversion be used for all materials?
The conversion is valid when the material thickness is uniform and temperature gradients are consistent; heterogeneous materials may require more detailed analysis.
