Thermal conductivity converter

How readily a material carries heat. 5 units, converted from one table of exact factors.

1 watt/meter·kelvin in every other thermal conductivity unit

Computed by the same engine that runs the converter above, so these can never drift apart from it.

What each unit actually is

Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
