Use the Btu per hour foot °F to Btu inches per hour square foot °F Converter
Btu per hour foot °F to Btu inches per hour square foot °F formula and what each symbol means
Btu·in/(h·ft²·°F) = Btu/(h·ft·°F) × 12
| Symbol | Meaning |
|---|---|
| Btu/(h·ft·°F) | Btu per hour foot °F |
| Btu·in/(h·ft²·°F) | Btu inch per hour square foot °F |
Btu per hour foot °F to Btu inches per hour square foot °F examples
1 Btu/(h·ft·°F)
1 Btu/(h·ft·°F) × 12 = 12 Btu·in/(h·ft²·°F).
10 Btu/(h·ft·°F)
10 Btu/(h·ft·°F) × 12 = 120 Btu·in/(h·ft²·°F).
100 Btu/(h·ft·°F)
100 Btu/(h·ft·°F) × 12 = 1,200 Btu·in/(h·ft²·°F).
Btu per hour foot °F compared with Btu inches per hour square foot °F
One Btu/(h·ft·°F) is 12 times as large as one Btu·in/(h·ft²·°F), so your number gets bigger when you convert Btu per hour foot °F to Btu inches per hour square foot °F and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About Btu per hour foot °F and Btu inches per hour square foot °F
Btu per hour foot °F (Btu/(h·ft·°F)): A US customary unit, about 1.7307 W/(m·K). Btu inch per hour square foot °F (Btu·in/(h·ft²·°F)): A US customary unit used for insulation data, about 0.14423 W/(m·K).
How to calculate Btu per hour foot °F to Btu inches per hour square foot °F step by step
- Enter the value in Btu/(h·ft·°F) (the starting unit).
- Multiply by 12, because 1 Btu/(h·ft·°F) = 12 Btu·in/(h·ft²·°F).
- The product is the value in Btu·in/(h·ft²·°F). To go back, divide by 12 or multiply by 0.08333333.
