In my particular case, I'm building a tiny shed. I'm using ungrooved 3/4 inch treated plywood and no glue, if that makes a difference.
I'm not sure what the relevant units are either. Pounds per square foot? Screws per 4'x8' sheet?

According to Table R602.3(1) of International Residential Code (IRC), subfloor fastener schedule is as follows:
3/8"-1/2" panels. Use 6d common nails, spaced 6" apart on edges and 12" apart in the field.
19/32"-1" panels. Use 8d common nails, spaced 6" apart on edges and 12" apart in the field.
1 1/8"-1 1/4" panels. Use 10d common or 8d deformed nails, spaced 6" apart on edges and 12" apart in the field.
