How to Convert Watt per Square Centimetre Kelvin to cal/(s·cm²·°C)
- 1 W/(cm²·K) = 0.2390057361 cal/(s·cm²·°C)
- 1 cal/(s·cm²·°C) = 4.184 W/(cm²·K)
- Example: convert 15 W/(cm²·K) to cal/(s·cm²·°C): 15 W/(cm²·K) = 15 × 0.2390057361 cal/(s·cm²·°C) = 3.585086042 cal/(s·cm²·°C)
Reference conditions. cal/(s·cm²·°C): Thermochemical calorie (4.184 J)
Formula
cal/(s·cm²·°C) = W/(cm²·K) × 0.2390057361377
or cal/(s·cm²·°C) = W/(cm²·K) ÷ 4.184
Derivation from SI units:
- 1 W/(cm²·K) = 10 000 W/(m²·K)
- 1 cal_th/(s·cm²·°C) = 4.184 J ÷ (1 s × 10⁻⁴ m² × 1 K) = 41 840 W/(m²·K) (exact)
- 1 W/(cm²·K) = 10000 W/(m²·K) ÷ 41840 W/(m²·K) per cal/(s·cm²·°C) = 0.2390057361377 cal/(s·cm²·°C)
Both units are defined exactly, so the factor is exact. Watt per Square Centimetre Kelvin definition: watt per square centimetre kelvin; cal/(s·cm²·°C) definition: calorie per second square centimetre degree Celsius.
Worked examples
- A reading of 0.1 W/(cm²·K) converts to 0.02390057361 cal/(s·cm²·°C).
0.1 W/(cm²·K) × 0.2390057361 = 0.02390057361 cal/(s·cm²·°C) - A value of 2 W/(cm²·K) is 0.4780114723 cal/(s·cm²·°C).
2 W/(cm²·K) × 0.2390057361 = 0.4780114723 cal/(s·cm²·°C)

Where it's used
Watts per Square Centimetre Kelvin are used for electronics and microchannel cooling, 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.
