Question

The SI unit of thermal conductivity is

a) JS-1m

-1K

-1 b) JSm-1K

c) JSm-1K

-1 d) JS-1mK​

Answer 1

Answer:

W/(m⋅K) is the true answer.

Answer 2

Answer:

JS/m⋅1K

Explanation:

watts per

Units. In the International System of Units (SI), thermal conductivity is measured in watts per meter-kelvin (W/(m⋅K)). Some papers report in watts per centimeter-kelvin (W/(cm⋅K)). In imperial units, thermal conductivity is measured in BTU/(h⋅ft⋅°F).

And W = JS

So.... Answer is : JS/m⋅1K
