Btu (th) foot/hour/sq. foot/°F to watt/meter/K
Please provide values below to convert Btu (th) foot/hour/sq. foot/°F to watt/meter/K [W/(m*K)], or change ↔.
Btu (th) foot/hour/sq. foot/°F
Definition: Similar to the IT-based Btu unit but using thermochemical Btu for heat transfer measurements.
Historyandorigin: A historically used unit in North American systems.
CurrentUse: Mostly obsolete but still found in some legacy applications.
funfact: Though less common now, it's interesting to see how old systems were calibrated with different definitions of Btu!
watt/meter/K [W/(m*K)]
Definition: A unit of thermal conductivity that measures how much heat passes through a meter of material when a 1K temperature difference is maintained.
Historyandorigin: The SI unit of thermal conductivity, derived from Joules per second per meter per Kelvin.
CurrentUse: Used in material science, engineering, and building construction to assess heat conduction.
funfact: A material with a high thermal conductivity will feel hot to the touch quickly, like metals!

How to Convert Btu (th) foot/hour/sq. foot/°F to watt/meter/K
1 Btu (th) foot/hour/sq. foot/°F = 1.7295772055 watt/meter/K [W/(m*K)]
1 watt/meter/K [W/(m*K)] = 0.5781759824 Btu (th) foot/hour/sq. foot/°F
we use cross multiplication method
Btu (th) foot/hour/sq. foot/°F → watt/meter/K [W/(m*K)]
1 → 1.7295772055
1.5 → ?( suppose x)
=>1.5*1.7295772055=1*x
by simplifying
x=2.5943658083
