Convert Watts per Centimetre Kelvin to mW/(m·K)
1 watt per centimetre kelvin (W/(cm·K)) = 100000 milliwatts per metre kelvin (mW/(m·K)). 1 mW/(m·K) = 0.00001 W/(cm·K). Example: 15 W/(cm·K) = 15 × 100000 = 1500000 mW/(m·K).

How to Convert Watt per Centimetre Kelvin to Milliwatt per Metre Kelvin
- 1 W/(cm·K) = 100000 mW/(m·K)
- 1 mW/(m·K) = 0.00001 W/(cm·K)
- Example: convert 15 W/(cm·K) to mW/(m·K): 15 W/(cm·K) = 15 × 100000 mW/(m·K) = 1500000 mW/(m·K)
Formula
mW/(m·K) = W/(cm·K) × 100000
Derivation from SI units:
- 1 W/(cm·K) = 100 W/(m·K)
- 1 mW/(m·K) = 0.001 W/(m·K)
- 1 W/(cm·K) = 100 W/(m·K) ÷ 0.001 W/(m·K) per mW/(m·K) = 100000 mW/(m·K)
Both units are defined exactly, so the factor is exact. Watt per Centimetre Kelvin definition: watt per centimetre kelvin; Milliwatt per Metre Kelvin definition: milliwatt per metre kelvin.
Worked examples
- A reading of 1 W/(cm·K) converts to 100000 mW/(m·K).
1 W/(cm·K) × 100000 = 100000 mW/(m·K) - A value of 2.37 W/(cm·K) is 237000 mW/(m·K).
2.37 W/(cm·K) × 100000 = 237000 mW/(m·K)
