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.
| From | Equals | Unit |
|---|---|---|
| 1 watt/meter·kelvin | 0.001 | kilowatt/meter·kelvin (kW/(m·K)) |
| 1 watt/meter·kelvin | 0.002390057361 | calorie/second·centimeter·°C (cal/(s·cm·°C)) |
| 1 watt/meter·kelvin | 0.5777893167 | BTU/hour·foot·°F (Btu/(h·ft·°F)) |
| 1 watt/meter·kelvin | 6.933471797 | BTU·inch/hour·foot²·°F (Btu·in/(h·ft²·°F)) |
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.
| Unit | Symbol | What it actually is |
|---|---|---|
| watt/meter·kelvin | W/(m·K) | SI. Copper is about 400, air about 0.026. |
| kilowatt/meter·kelvin | kW/(m·K) | |
| calorie/second·centimeter·°C | cal/(s·cm·°C) | |
| BTU/hour·foot·°F | Btu/(h·ft·°F) | The US engineering unit. |
| BTU·inch/hour·foot²·°F | Btu·in/(h·ft²·°F) | Insulation is quoted this way. |
