How to convert Btu IT per square foot to thermochemical calories per square centimeter
This family follows the heat-per-surface-area convention J/m². Volumetric heat density J/m³ would need a thickness to relate to it. Energy density is not a rate of heat flow.
Use x for the value in Btu IT/ft², b for the intermediate value in J/m², and y for the result in cal/cm².
cal/cm² = Btu IT/ft² × 11356.526682226975 ÷ 41840
Worked examples
10 Btu IT/ft² ≈ 2.71427501965 cal/cm²
Step 1: (10 × 11356.5266822) ≈ 113565.266822 J/m².
Step 2: 113565.266822 ÷ 41840 ≈ 2.71427501965 cal/cm².20 Btu IT/ft² ≈ 5.42855003931 cal/cm²
Step 1: (20 × 11356.5266822) ≈ 227130.533645 J/m².
Step 2: 227130.533645 ÷ 41840 ≈ 5.42855003931 cal/cm².
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Btu IT per square foot
