Rendered to 6 significant figures.
Formula
Formula
K/MW = K/W × 1000000
Multiply any value in kelvins per watt by 1000000 to obtain the value in kelvins per megawatt.
Worked example
Convert 1 K/W to K/MW.
- 01Start with 1 K/W.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 K/MW.
Result1 K/W = 1.00000e+6 K/MW

FAQ
What is the conversion factor from K/W to K/MW?
1 K/W equals 1000000 K/MW. To convert, multiply the value in kelvins per watt by 1000000.
How do I convert 1 K/W to K/MW?
1 K/W = 1.00000e+6 K/MW. For any value, multiply by 1000000.
How do I convert K/MW back to K/W?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 K/MW = 1e-6 K/W.
When would I need to convert kelvin per watt to kelvin per megawatt?
Thermal-resistance conversions between K/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).
