Thermal Conductivity Converter
Watt/meter-kelvin (W/m·K)
Definition: The SI unit for thermal conductivity. It represents the rate of heat flow (Watts) through a material of unit thickness (meter) per unit of temperature difference (Kelvin).
History/origin: Established as part of the SI system to create a direct link between power (Watts), distance, and temperature change in thermodynamic calculations.
Current use: The absolute standard in physics, global engineering, and material science to define how well a material conducts heat.
Watt/centimeter-kelvin
Definition: A decimal multiple of the SI unit, often used when dealing with smaller components like semiconductor chips.
History/origin: Derived from the base SI unit to provide a more manageable scale for micro-electronics and laboratory-scale samples.
Current use: Frequently used in the electronics industry to specify the heat dissipation qualities of heat sinks and silicon wafers.

How to Convert Watt/meter-kelvin (W/m·K) to Watt/centimeter-kelvin
1 w_mk = 0.01 w_cmk
1 w_cmk = 100 w_mk
Example: convert 15 w_mk to w_cmk:
15 w_mk = 15 × 0.01 w_cmk = 0.15 w_cmk
Did You Know?
- Did you know? Diamond has the highest thermal conductivity of any naturally occurring bulk material, about 5 times higher than copper! This is why diamonds always feel cold to the touch.
