Find the conversion factor from BTU (IT) per hour square foot to Watt per square meter
1 BTU/(h·ft²) = 3.154590745 W/m²
factor = 3.154590745 ÷ 1 = 3.154590745 W/m² per BTU/(h·ft²)
Multiply by the factor: BTU/(h·ft²) cancels, leaving W/m²
W/m² = BTU/(h·ft²) × (W/m² per BTU/(h·ft²))
1 BTU/(h·ft²) × 3.154590745 W/m² per BTU/(h·ft²) = 3.154590745 W/m²
How it works
1 BTU/(h·ft²) = 3.154590745 W/m², so W/m² = BTU/(h·ft²) × 3.154590745
