### How to convert Watt/Square Meter to BTU/Hour Square Foot ?

1 watt/square meter (W/m²) is equal to 0.317 btu/hour square foot (BTU/h∙ft²).

1W/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 watt/square meter (W/m²) times 0.317, that conversion formula:

Ǿq(BTU/h∙ft²) = Ǿq(W/m²) × 0.317
