Thermal Resistance

mK/WtoK/MW

Convert millikelvins per watt (mK/W) to kelvins per megawatt (K/MW).

Factor1 mK/W = 1000 K/MW

Converter

mK/W

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

Result
1000K/MW

Rendered to 6 significant figures.

Formula

Formula
K/MW = mK/W × 1000

Multiply any value in millikelvins per watt by 1000 to obtain the value in kelvins per megawatt.

Worked example

Convert 1 mK/W to K/MW.

  1. 01Start with 1 mK/W.
  2. 02Multiply by the conversion factor: 1 × 1000 = 1000 K/MW.
Result1 mK/W = 1000 K/MW

FAQ

What is the conversion factor from mK/W to K/MW?
1 mK/W equals 1000 K/MW. To convert, multiply the value in millikelvins per watt by 1000.
How do I convert 1 mK/W to K/MW?
1 mK/W = 1000 K/MW. For any value, multiply by 1000.
How do I convert K/MW back to mK/W?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 K/MW = 0.001 mK/W.
When would I need to convert millikelvin per watt to kelvin per megawatt?
Thermal-resistance conversions between mK/W and K/MW 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).
