How to Convert cal/(s·cm²·°C) to Watt per Square Centimetre Kelvin
- 1 cal/(s·cm²·°C) = 4.184 W/(cm²·K)
- 1 W/(cm²·K) = 0.2390057361 cal/(s·cm²·°C)
- Example: convert 15 cal/(s·cm²·°C) to W/(cm²·K): 15 cal/(s·cm²·°C) = 15 × 4.184 W/(cm²·K) = 62.76 W/(cm²·K)
Reference conditions. cal/(s·cm²·°C): Thermochemical calorie (4.184 J)
Formula
W/(cm²·K) = cal/(s·cm²·°C) × 4.184
Derivation from SI units:
- 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) = 10 000 W/(m²·K)
- 1 cal/(s·cm²·°C) = 41840 W/(m²·K) ÷ 10000 W/(m²·K) per W/(cm²·K) = 4.184 W/(cm²·K)
Both units are defined exactly, so the factor is exact. cal/(s·cm²·°C) definition: calorie per second square centimetre degree Celsius; Watt per Square Centimetre Kelvin definition: watt per square centimetre kelvin.
Worked examples
- A reading of 0.001 cal/(s·cm²·°C) converts to 0.004184 W/(cm²·K).
0.001 cal/(s·cm²·°C) × 4.184 = 0.004184 W/(cm²·K) - A value of 0.05 cal/(s·cm²·°C) is 0.2092 W/(cm²·K).
0.05 cal/(s·cm²·°C) × 4.184 = 0.2092 W/(cm²·K)
