Kilowatt per Meter per Kelvin (kW/(m·K))
Definition: A larger-scale conductivity unit for describing extremely good thermal conductors, where the base watt-per-meter-kelvin figure would otherwise run into the thousands.
History: A straightforward SI multiple of watt per meter per kelvin, applied to high-conductivity materials like pure metals where kilowatt-scale figures are more convenient.
Current use: Occasionally used in industrial heat-exchanger and power-electronics contexts involving highly conductive metal components.
Watt per Centimeter per °C (W/(cm·°C))
Definition: A finer-scale metric conductivity unit sized for laboratory and small-component measurements, where thicknesses are naturally measured in centimeters rather than meters.
History: A natural CGS-scale variant of watt per meter per kelvin, used in physics and materials laboratories that work with centimeter-scale samples.
Current use: Common in materials-testing and semiconductor thermal characterization, where sample thicknesses are typically millimeters to centimeters rather than full meters.

About These Parameters
- Value
- The thermal conductivity value you want to convert, expressed in the "From" unit. Accepts decimals.
- From Unit
- The unit your input value is currently measured in — the SI W/(m·K), or a US insulation datasheet's Btu·in/(h·ft²·°F) k-value.
- To Unit
- The conductivity unit you want the result converted into. Use the swap button to flip From and To instantly.
How Thermal Conductivity Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to watts per meter per kelvin. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Kilowatt per Meter per Kelvin → Watt per Centimeter per °C: multiply by 10. For example, 1 kW/(m·K) × 10 = 10 W/(cm·°C).
Conductivity (k) vs. Resistance (R)
Thermal conductivity (this page) is a property of the material itself, independent of how thick a piece of it you have. R-value, printed on US insulation packaging, is the inverse relationship scaled by an actual thickness — a thicker layer of the same material has a higher R-value even though its conductivity k hasn't changed. That's why doubling a wall's insulation thickness roughly doubles its R-value, but has no effect at all on the insulation material's underlying k-value in W/(m·K) or Btu·in/(h·ft²·°F).
Conductors vs. Insulators
Thermal conductivity spans an enormous range: solid copper conducts heat at roughly 400 W/(m·K), while modern aerogel insulation can be as low as 0.015 W/(m·K) — a difference of over 25,000 times. Materials engineers reach for this converter constantly when comparing candidate materials sourced from different countries' datasheets, since the same underlying physical property is reported in wildly different-looking numbers depending on the unit convention used.
Example
A material with a conductivity of 1 kW/(m·K) equals 10 W/(cm·°C). For scale, common fiberglass batt insulation sits around 0.04 W/(m·K), while structural concrete is roughly 1.7 W/(m·K) — over 40 times more conductive, which is why concrete alone provides negligible insulation value.
Frequently Asked Questions
How many Watts per Centimeter per °C are in 1 Kilowatt per Meter per Kelvin?
1 Kilowatt per Meter per Kelvin (kW/(m·K)) equals exactly 10 Watts per Centimeter per °C (W/(cm·°C)).
Why does US insulation use inches instead of feet for its k-value?
Most rigid foam and batt insulation products are only a few inches thick, so measuring conductivity per inch of thickness keeps the resulting numbers in a convenient, easy-to-compare range rather than the smaller decimals a per-foot figure would produce for the same material.
Does thermal conductivity change with temperature?
Yes, for most materials conductivity varies somewhat with temperature (and for some materials, quite significantly). The conversion factors on this page relate different UNITS for the same measured value; they don't account for how a material's own conductivity might shift between measurement conditions.
How accurate are these conversions?
Every conversion factor used here is the exact, internationally recognized relationship between the underlying energy, length, area, and temperature units — results are limited only by floating-point display precision, not by rounded conversion constants.
