Formula
Formula
K/kW = µK/W × 0.001
Multiply any value in microkelvins per watt by 0.001 to obtain the value in kelvins per kilowatt.
Worked example
Convert 1000 µK/W to K/kW.
- 01Start with 1000 µK/W.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 K/kW.
Result1000 µK/W = 1 K/kW

FAQ
What is the conversion factor from µK/W to K/kW?
1 µK/W equals 0.001 K/kW. To convert, multiply the value in microkelvins per watt by 0.001.
How do I convert 1 µK/W to K/kW?
1 µK/W = 0.001 K/kW. For any value, multiply by 0.001.
How do I convert K/kW back to µK/W?
Divide by the same factor — or equivalently, multiply by 1000. So 1 K/kW = 1000 µK/W.
When would I need to convert microkelvin per watt to kelvin per kilowatt?
Thermal-resistance conversions between µK/W and K/kW appear in electronics cooling (heat-sink and TIM datasheets), transformer, motor and generator thermal-rise calculations, lumped-element R-C thermal-network modelling, and transient heat-transfer analysis. K/W and °C/W are the SI standard; mK/W and µK/W cover sub-SI heat-sink and TIM datasheet ladders; K/kW and K/MW cover large-equipment and power-plant notation; °F·h/BTU and °F·s/BTU are the US convention. This category is lumped thermal resistance only — it does NOT include area-normalized R-value (m²·K/W), thermal-conductivity inverse with geometry, or U-value calculations, all of which are different physical quantities.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
