Find the conversion factor from BTU (IT) per square foot to Kilojoule per square meter
1 BTU/ft² = 11,356.52668 J/m² · 1 kJ/m² = 1,000 J/m²
factor = 11,356.52668 ÷ 1,000 = 11.35652668 kJ/m² per BTU/ft²
Multiply by the factor: BTU/ft² cancels, leaving kJ/m²
kJ/m² = BTU/ft² × (kJ/m² per BTU/ft²)
1 BTU/ft² × 11.35652668 kJ/m² per BTU/ft² = 11.35652668 kJ/m²
How it works
1 BTU/ft² = 11.35652668 kJ/m², so kJ/m² = BTU/ft² × 11.35652668
