Frequently Asked Questions
-
What does Btu (IT) foot/hour/sq. foot/°F measure?
-
It measures thermal conductivity as heat flow through a material one foot thick with a one square foot cross-section for each degree Fahrenheit temperature difference.
-
Why convert to kilocalorie (IT)/hour/meter/°C?
-
Converting to this unit allows comparison and analysis of thermal conductivity using non-SI metric units common in certain engineering fields and regional standards.
-
Are these conversions exact for all materials?
-
Conversions assume steady-state conditions and uniform materials; real conditions may introduce variability.
