About Thermal Conductivity conversion
Thermal conductivity is watts per meter-kelvin (SI) and BTU per hour-foot-degree-F (US), insulation at 0.03 W/m·K and copper at 385 W/m·K. Fiction Units converts between them.
One W/m·K is about 0.578 BTU/hr·ft·°F, the scale that links lab datasheets to US specs.
Units supported: W/m·K, BTU/hr·ft·°F, cal/s·cm·°C (copper ~385 W/m·K).
