How to Convert Watt per Centimetre Kelvin to cal/(s·cm·°C)
- 1 W/(cm·K) = 0.2390057361 cal/(s·cm·°C)
- 1 cal/(s·cm·°C) = 4.184 W/(cm·K)
- Example: convert 15 W/(cm·K) to cal/(s·cm·°C): 15 W/(cm·K) = 15 × 0.2390057361 cal/(s·cm·°C) = 3.585086042 cal/(s·cm·°C)
Reference conditions. cal/(s·cm·°C): Thermochemical calorie (4.184 J)
Formula
cal/(s·cm·°C) = W/(cm·K) × 0.2390057361377
or cal/(s·cm·°C) = W/(cm·K) ÷ 4.184
Derivation from SI units:
- 1 W/(cm·K) = 100 W/(m·K)
- 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) ÷ 418.4 W/(m·K) per cal/(s·cm·°C) = 0.2390057361377 cal/(s·cm·°C)
Both units are defined exactly, so the factor is exact. Watt per Centimetre Kelvin definition: watt per centimetre kelvin; cal/(s·cm·°C) definition: calorie per second centimetre degree Celsius.
Worked examples
- A reading of 1 W/(cm·K) converts to 0.2390057361 cal/(s·cm·°C).
1 W/(cm·K) × 0.2390057361 = 0.2390057361 cal/(s·cm·°C) - A value of 2.37 W/(cm·K) is 0.5664435946 cal/(s·cm·°C).
2.37 W/(cm·K) × 0.2390057361 = 0.5664435946 cal/(s·cm·°C)
