Convert btu inch per hour ft² °fs to milliwatt per meter kelvins
1 BTU·in/(h·ft²·°F) = 144.227888864 mW/(m·K) — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
How to convert btu inch per hour ft² °fs to milliwatt per meter kelvins
Multiply the number of btu inch per hour ft² °fs by 144.227888864 to get milliwatt per meter kelvins.
BTU inch per hour ft² °F: The "k-value" on US insulation datasheets.
Milliwatt per meter kelvin: Insulation and aerogels live down here — still air is about 26 mW/(m·K).
