How to Convert cal/(s·cm·°C) to Watt per Centimetre Kelvin
- 1 cal/(s·cm·°C) = 4.184 W/(cm·K)
- 1 W/(cm·K) = 0.2390057361 cal/(s·cm·°C)
- Example: convert 15 cal/(s·cm·°C) to W/(cm·K): 15 cal/(s·cm·°C) = 15 × 4.184 W/(cm·K) = 62.76 W/(cm·K)
Reference conditions. cal/(s·cm·°C): Thermochemical calorie (4.184 J)
Formula
W/(cm·K) = cal/(s·cm·°C) × 4.184
Derivation from SI units:
- 1 cal_th/(s·cm·°C) = 4.184 J ÷ (1 s × 0.01 m × 1 K) = 418.4 W/(m·K) (exact)
- 1 W/(cm·K) = 100 W/(m·K)
- 1 cal/(s·cm·°C) = 418.4 W/(m·K) ÷ 100 W/(m·K) per W/(cm·K) = 4.184 W/(cm·K)
Both units are defined exactly, so the factor is exact. cal/(s·cm·°C) definition: calorie per second centimetre degree Celsius; Watt per Centimetre Kelvin definition: watt per centimetre kelvin.
Worked examples
- A reading of 0.005 cal/(s·cm·°C) converts to 0.02092 W/(cm·K).
0.005 cal/(s·cm·°C) × 4.184 = 0.02092 W/(cm·K) - A value of 0.1 cal/(s·cm·°C) is 0.4184 W/(cm·K).
0.1 cal/(s·cm·°C) × 4.184 = 0.4184 W/(cm·K)
