1. Is there a difference between saying kilogram metres per second

and kilograms per metre per second?

besides the extra per and loss of s after metre in the second phrase is there a difference?
2. If I'm not mistaken, kg per meter per second is also kgs/m because when you divide by a value, its also the same a multiplying by the reciprocal.

Without any brackets to specify, that's read as kilograms metres per second is kgm/s.

kilograms per metre per second is read as kg/(ms)

kilograms per metre per second is read as kg/(ms)
i would've thought that mean kg/m/s instead?

Nopes. You read acceleration as metres per second per second. This mean m/(ss) = m/(s^2). Not m/(s/s) = m... That's nonsensical.
