### How to convert Joule/Second Square Meter to BTU/Hour Square Foot ?

1 joule/second square meter (J/s∙m²) is equal to 0.317 btu/hour square foot (BTU/h∙ft²).

1J/s∙m² = 0.317BTU/h∙ft²

The heat flux density Ǿq in btu/hour square foot (BTU/h∙ft²) is equal to the heat flux density Ǿq in joule/second square meter (J/s∙m²) times 0.317, that conversion formula:

Ǿq(BTU/h∙ft²) = Ǿq(J/s∙m²) × 0.317
