How the conversion works

The input is converted into W/m² using the source factor and offset, then into BTU IT per hour square foot. This keeps unit definitions consistent across the heat flux collection.

Definitions and sources

Factors are maintained in the versioned unit dataset. Output is rounded to your selected significant digits; calculation uses JavaScript double precision.
