Not quite.
Standard bolt sizes are notated as "diameter - threads per inch", so 1/2'' - 20 is a 1/2'' diameter bolt with 20 threads per inch.
Note that for smaller sizes, the first number may be given without units (such as "10-32"). This refers to machine screw size, (in this case, a #10), and if you want to know the diameter in inches you can just look it up (in this case, it'd be ~.19''). It helps to have a wall chart in your build space for this.
