Please provide values below to convert Btu (IT) inch/second/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F, or change ↔.
Btu (IT) inch/second/sq. foot/°F
Definition: Measures thermal conductivity using British thermal units (IT) with an inch of material thickness, per second, and per square foot.
Historyandorigin: An imperial-based unit, historically used in North American heating systems.
CurrentUse: Used in HVAC systems, especially in residential and commercial buildings in the US.
funfact: You can find this unit in the specifications of insulation and building materials in the US!
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!

How to Convert Btu (IT) inch/second/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F
1 Btu (IT) inch/second/sq. foot/°F = 300.20076482 Btu (th) foot/hour/sq. foot/°F
1 Btu (th) foot/hour/sq. foot/°F = 0.0033311041 Btu (IT) inch/second/sq. foot/°F
we use cross multiplication method
Btu (IT) inch/second/sq. foot/°F → Btu (th) foot/hour/sq. foot/°F
1 → 300.20076482
1.5 → ?( suppose x)
=>1.5*300.20076482=1*x
by simplifying
x=450.30114723
