About International table BTU per hour per square foot
The international table BTU per hour per square foot (BTU(IT)/(h·ft²)) equals 1055.05585262/(3600×0.09290304) ≈ 3.15459 W/m². The standard US heat flux unit in ASHRAE, ASTM, and building codes for thermal resistance (R-value), boiler ratings, and heat exchanger design. 1 BTU(IT)/(h·ft²) ≈ 3.15459 W/m².
About International table calorie per second per square centimetre
The international table calorie per second per square centimetre (cal(IT)/(s·cm²)) equals exactly 41868 W/m² (1 cal(IT) = 4.1868 J; 1 cm² = 10⁻⁴ m²). The IT variant of the high-flux CGS unit, slightly larger than the thermochemical counterpart due to the IT calorie definition. 1 cal(IT)/(s·cm²) = 41868 W/m².
