Btu (IT) inch/hour/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F
Please provide values below to convert Btu (IT) inch/hour/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F, or change ↔.
Btu (IT) inch/hour/sq. foot/°F
Definition: Indicates heat transfer in Btu (IT) across one inch of material per hour per square foot.
Historyandorigin: Used to describe smaller-scale heat flows, particularly in heating systems with thin insulation.
CurrentUse: Relevant for calculating heat loss or gain in walls, windows, and other thin materials.
funfact: This unit is especially useful for calculating insulation efficiency in colder climates!
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/hour/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F
1 Btu (IT) inch/hour/sq. foot/°F = 0.0833891013 Btu (th) foot/hour/sq. foot/°F
1 Btu (th) foot/hour/sq. foot/°F = 11.991974778 Btu (IT) inch/hour/sq. foot/°F
we use cross multiplication method
Btu (IT) inch/hour/sq. foot/°F → Btu (th) foot/hour/sq. foot/°F
1 → 0.0833891013
1.5 → ?( suppose x)
=>1.5*0.0833891013=1*x
by simplifying
x=0.125083652
