Thermal Resistance

°C/WtoµK/W

Convert degrees Celsius per watt (°C/W) to microkelvins per watt (µK/W).

Factor1 °C/W = 1000000 µK/W

Converter

°C/W

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1.00000e+6µK/W

Rendered to 6 significant figures.

Formula

Formula
µK/W = °C/W × 1000000

Multiply any value in degrees Celsius per watt by 1000000 to obtain the value in microkelvins per watt.

Worked example

Convert 1 °C/W to µK/W.

  1. 01Start with 1 °C/W.
  2. 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 µK/W.
Result1 °C/W = 1.00000e+6 µK/W

FAQ

What is the conversion factor from °C/W to µK/W?
1 °C/W equals 1000000 µK/W. To convert, multiply the value in degrees Celsius per watt by 1000000.
How do I convert 1 °C/W to µK/W?
1 °C/W = 1.00000e+6 µK/W. For any value, multiply by 1000000.
How do I convert µK/W back to °C/W?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 µK/W = 1e-6 °C/W.
When would I need to convert degree Celsius per watt to microkelvin per watt?
Thermal-resistance conversions between °C/W and µK/W 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).
