Frequently Asked Questions

What is thermal conductivity and why is it important?

Thermal conductivity measures a material’s ability to conduct heat. It’s crucial for designing thermal insulation, heat exchangers, electronic cooling systems, and understanding material properties in various temperature conditions.

What’s the difference between IT and thermochemical units?

International Table (IT) calorie = 4.1868 J exactly, while thermochemical calorie = 4.184 J. Similarly, IT Btu = 1055.06 J vs. thermochemical Btu = 1054.35 J. These small differences matter in precise engineering calculations.

How do I convert between SI and imperial thermal conductivity units?

1 W/(m·K) = 0.5779 Btu·ft/(hr·ft²·°F). Our converter handles all such conversions automatically – just select your input and output units.

Why are there so many Btu-based units?

Different industries use different combinations of length and time units with Btu. We include all common variants: per second/hour and per inch/foot combinations to cover all engineering needs.

What’s a typical thermal conductivity value for common materials?

Copper: ~400 W/(m·K), Steel: ~50 W/(m·K), Water: ~0.6 W/(m·K), Air: ~0.025 W/(m·K). These values help put the conversion results in context.
