Recently, I work on how to calculate the radiation by finite volume method.
In this method, an absorption coefficient is needed. I got the absorption coefficient from NASA-SP-3080.But the unit of absorbtion coeficient
is inverse centimeter(1/cm).My question is : if I want to use it in meter unit system, the unit of absorbtion coeficient (1/cm) should be change to inverse meter(1/m)? That mean the absorption coefficient(1/m) is the product of 100 times absorption coefficient (1/cm) from NASA-SP-3080?

Thank you in advance.

That's right: an absorption coefficient of 1/cm, say, = 100/m. This can easily be understood, since the power absorbed crossing 100 cm is 100 larger than for 1cm.
