Formula

Formula
BTU/(hr·ft²) = kBTU/(hr·ft²) × 1000

Multiply any value in kilo-British thermal units per hour-square foot by 1000 to obtain the value in British thermal units per hour-square foot.

Worked example

Convert 1 kBTU/(hr·ft²) to BTU/(hr·ft²).

  1. 01Start with 1 kBTU/(hr·ft²).
  2. 02Multiply by the conversion factor: 1 × 1000 = 1000 BTU/(hr·ft²).
Result1 kBTU/(hr·ft²) = 1000 BTU/(hr·ft²)

FAQ

What is the conversion factor from kBTU/(hr·ft²) to BTU/(hr·ft²)?
1 kBTU/(hr·ft²) equals 1000 BTU/(hr·ft²). To convert, multiply the value in kilo-British thermal units per hour-square foot by 1000.
How do I convert 1 kBTU/(hr·ft²) to BTU/(hr·ft²)?
1 kBTU/(hr·ft²) = 1000 BTU/(hr·ft²). For any value, multiply by 1000.
How do I convert BTU/(hr·ft²) back to kBTU/(hr·ft²)?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 BTU/(hr·ft²) = 0.001 kBTU/(hr·ft²).
When would I need to convert kilo-British thermal unit per hour-square foot to British thermal unit per hour-square foot?
Heat-flux conversions between kBTU/(hr·ft²) and BTU/(hr·ft²) appear in radiative-heat-transfer analysis, furnace and reactor design, electronics cooling, and solar-energy calculations. W/m² is the SI standard; BTU/(hr·ft²) and kcal/(hr·m²) appear in US and legacy European datasheets.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
