Unit of thermal conductivity and CTE
(OP)
I find the units of thermal conductivity and CTE are 'ppm', how can I convert if to W/mC and um/m/C?
Thank you very much.

RE: Unit of thermal conductivity and CTE
CTE, coefficient of thermal expansion (linear) is expressed as a fractional increment per oC (or oF). Since it is very small, often given in units 10-6/oC, which could be written as ppmlength/oC = um/m/C.

Dear kenvlach: Thanks for you help. How about the thermal conductivity? I can't convert the unit "ppm" to "W/m-K" because thermal conductivity is not a ratio.
RE: Unit of thermal conductivity and CTE
Thermal conductivity is given in W /(m.K).
The linear coefficient of thermal expansion ppm/K, is given in
10-6m /(m.K) .
Although both have the same divisor, they are not interconvertible because they are different entities.
