If you are ever trying to convert it, just divide 6080 by the first number (16, for example). Why 6080? Because that's how many feet are in a nautical mile.
So 6080/16=380. Therefore 16:1=380ft/NM
And if you are trying to convert the other way (from ft/NM to climb gradient as a ratio) it's the same thing. Divide 6080 by the ft to climb per nautical mile.
So 6080/380=16. 380ft/NM=16:1
