How to Convert kcal/(h·m²·°C) to cal/(s·cm²·°C)
- 1 kcal/(h·m²·°C) = 0.00002779636711 cal/(s·cm²·°C)
- 1 cal/(s·cm²·°C) = 35975.92433 kcal/(h·m²·°C)
- Example: convert 15 kcal/(h·m²·°C) to cal/(s·cm²·°C): 15 kcal/(h·m²·°C) = 15 × 0.00002779636711 cal/(s·cm²·°C) = 0.0004169455067 cal/(s·cm²·°C)
Reference conditions. kcal/(h·m²·°C): International Table kilocalorie (4186.8 J), as used in engineering heat transfer data cal/(s·cm²·°C): Thermochemical calorie (4.184 J)
Formula
cal/(s·cm²·°C) = kcal/(h·m²·°C) × 0.00002779636711281
or cal/(s·cm²·°C) = kcal/(h·m²·°C) ÷ 35975.92433362
Derivation from SI units:
- 1 kcal_IT/(h·m²·°C) = 4186.8 J ÷ (3600 s × 1 m² × 1 K) = 1.163 W/(m²·K) (exact)
- 1 cal_th/(s·cm²·°C) = 4.184 J ÷ (1 s × 10⁻⁴ m² × 1 K) = 41 840 W/(m²·K) (exact)
- 1 kcal/(h·m²·°C) = 1.163 W/(m²·K) ÷ 41840 W/(m²·K) per cal/(s·cm²·°C) = 0.00002779636711281 cal/(s·cm²·°C)
Both units are defined exactly, so the factor is exact. kcal/(h·m²·°C) definition: kilocalorie per hour square metre degree Celsius; cal/(s·cm²·°C) definition: calorie per second square centimetre degree Celsius.
Worked examples
- A reading of 20 kcal/(h·m²·°C) converts to 0.0005559273423 cal/(s·cm²·°C).
20 kcal/(h·m²·°C) × 0.00002779636711 = 0.0005559273423 cal/(s·cm²·°C) - A value of 500 kcal/(h·m²·°C) is 0.01389818356 cal/(s·cm²·°C).
500 kcal/(h·m²·°C) × 0.00002779636711 = 0.01389818356 cal/(s·cm²·°C)

Where it's used
kcal/(h·m²·°C) are used for older metric heat exchanger and boiler data, while calories per second square centimetre degree Celsius appear in older scientific and metallurgical literature. Both measure heat transfer coefficient (h) and thermal transmittance (U-value), so the conversion is a fixed factor.
