mK/WtoK/kW

1 mK/W equals 1 K/kW. To convert, multiply the value in millikelvins per watt by 1.

1 mK/W = 1 K/kW. For any value, multiply by 1.

Divide by the same factor — or equivalently, multiply by 1. So 1 K/kW = 1 mK/W.

Thermal-resistance conversions between mK/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.

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).
