How to change 2D wave spectrum unit (from m^2s/rad to m^2/(Hz degree)

hey matlab users,

I need to change the unit of my 2D wave spectrum from m^2s/rad to m^2/(Hz degree) but i don't know how do it!

if I divide for 2*pi I can convert s/rad to 1/Hz but in this way i obtain m^2/Hz ad not m^2/(Hz degree). How can I do it correctly?

Thank you all for your help!!

This isn't really a Matlab question, but let's go for it:

• m^2 is staying, so nothing needs to be done here
• Hz is 1/s, so s is 1/Hz, so no factor required
• 1/rad is 1/(360/2pi degrees), so that requires a factor of pi/180

So multiplying your data by pi/180 will convert m^2s/rad to m^2/(Hz degree).
