FAQ

What is the conversion factor from °F·s/BTU to K/MW?
1 °F·s/BTU equals 526.5651 K/MW. To convert, multiply the value in Fahrenheit-seconds per British thermal unit by 526.5651.
How do I convert 1 °F·s/BTU to K/MW?
1 °F·s/BTU = 526.565 K/MW. For any value, multiply by 526.5651.
How do I convert K/MW back to °F·s/BTU?
Divide by the same factor — or equivalently, multiply by 0.001899101. So 1 K/MW = 0.0018991 °F·s/BTU.
When would I need to convert Fahrenheit-second per British thermal unit to kelvin per megawatt?
Thermal-resistance conversions between °F·s/BTU 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).
