Is there a wat to transform kg/m2h to m/s

I'm not sure if kg/m2h is for Evaporation coefficient, Water flux,Drying rate or Mass transfer coefficient. However one of the can be transform to m/s (maybe Impingement velocity)

I don't see how you would do that. You are talking about base units in the SI system (except for hours which is easily replaced by seconds). There's no direct conversion.

kg/m2h is a mass flux of a substance through an area
m/s is the linear velocity of that substance

Therefore, step 1 is to convert the mass flow to volumetric flow (divide by density).
then you'll need to realize that:
m3/m2h = 1 m/h
so, the volume passing through an area per time equals linear velocity.

Then divide by 3600 to get the /h in stead of /s. (3600 seconds in 1 hour).

That's a calculation, not a conversion/transformation. I guess I shouldn't take the posts so literally.

Hehe... you probably shouldn't. On internet you can never be sure you're talking to a native English speaker (who can be expected to choose exactly the right words) or someone (like me) who is merely likely to choose the right words :D
