Please provide values below to convert Btu (th) inch/second/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F, or change ↔.
Btu (th) inch/second/sq. foot/°F
Definition: Similar to the IT-based Btu, but based on the thermochemical definition of Btu.
Historyandorigin: A variation used in traditional thermodynamic studies before the adoption of IT-Btu.
CurrentUse: Mainly found in legacy industrial and building specifications.
funfact: Older systems often calculated heat loss and gain with this variation of Btu, even though it's not as common today.
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 (th) inch/second/sq. foot/°F to Btu (th) foot/hour/sq. foot/°F
1 Btu (th) inch/second/sq. foot/°F = 300 Btu (th) foot/hour/sq. foot/°F
1 Btu (th) foot/hour/sq. foot/°F = 0.0033333333 Btu (th) inch/second/sq. foot/°F
we use cross multiplication method
Btu (th) inch/second/sq. foot/°F → Btu (th) foot/hour/sq. foot/°F
1 → 300
1.5 → ?( suppose x)
=>1.5*300=1*x
by simplifying
x=450
