How to convert thermochemical calories per square centimeter to Btu IT per square foot
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 cal/cm², b for the intermediate value in J/m², and y for the result in Btu IT/ft².
Btu IT/ft² = cal/cm² × 41840 ÷ 11356.526682226975
Worked examples
10 cal/cm² ≈ 36.8422504263 Btu IT/ft²
Step 1: (10 × 41840) ≈ 418400 J/m².
Step 2: 418400 ÷ 11356.5266822 ≈ 36.8422504263 Btu IT/ft².20 cal/cm² ≈ 73.6845008527 Btu IT/ft²
Step 1: (20 × 41840) ≈ 836800 J/m².
Step 2: 836800 ÷ 11356.5266822 ≈ 73.6845008527 Btu IT/ft².
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 Thermochemical calories per square centimeter
