Formula

Formula
K/(BTU/h) = mK/W × 0.0002930711

Multiply any value in millikelvins per watt by 0.0002930711 to obtain the value in kelvins per BTU per hour.

Worked example

Convert 1000 mK/W to K/(BTU/h).

  1. 01Start with 1000 mK/W.
  2. 02Multiply by the conversion factor: 1000 × 0.0002930711 = 0.293071 K/(BTU/h).
Result1000 mK/W = 0.293071 K/(BTU/h)

FAQ

What is the conversion factor from mK/W to K/(BTU/h)?
1 mK/W equals 0.0002930711 K/(BTU/h). To convert, multiply the value in millikelvins per watt by 0.0002930711.
How do I convert 1 mK/W to K/(BTU/h)?
1 mK/W = 0.000293071 K/(BTU/h). For any value, multiply by 0.0002930711.
How do I convert K/(BTU/h) back to mK/W?
Divide by the same factor — or equivalently, multiply by 3412.142. So 1 K/(BTU/h) = 3412.14 mK/W.
When would I need to convert millikelvin per watt to kelvin per BTU per hour?
Thermal-resistance conversions between mK/W and K/(BTU/h) 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).
