Major (outside) thread diameter. The number gives the thickness only; length and thread pitch are separate (8-32 × 1/2" is a #8, 32 threads per inch, half an inch long).
The math
How to convert in to screw
Diameter (in) = 0.060 + 0.013 × number; for #00 use −1, #000 −2. Millimeters = inches × 25.4.
Example: 0.19 in = #10 screw.
