The capacity of a 16oz. glass jar is approximately No. 303 tin can.

The capacity of a No. 2.5 glass jar is approximately the same as the No. 2.5 tin can.

Explanation of Dimensional Food Can Standards
Metal can sizes used in industry in the U.S.A. are derived from nominal
outside dimensions. Measurements are made of the empty round can before seaming on the
packers' end.
While such dimensions may be expressed in inches, the custom is to use a
conventionalized method in which threedigit numbers are used to express each
dimension. The first digit indicates the number of whole inches in a dimension,
and the second and third digits indicate the fractional inches as sixteenths of an inch.
Thus:
303 x 406 means 33/16 x 46/16 inches
307 x 512 means 37/16 x 512/16 inches
603 x 700 means 63/16 x 7 inches
The first threedigit number describing a round can indicates the diameter measured
across the outside of the chime on the seamed end. The second threedigit number indicates the overall
height of the can with one end on.
In stating the dimensions of oval, obround, or obrotund cans, outside dimensions are used,
the dimensions of the opening stated first, followed by the height. Thus, there will be three sets
of figures: the first two being the long and short axis of the opening. Their interpretation in inches and
sixteenths of an inch is the same as with round cans. An oval can might have the size given as 402 x 304 x 612,
which would mean that the oval opening was 42/16 x 34/16 inches and the height was 612/16 inches.
In the table below the "No. 2 Equivalent" indicates the number of No. 2 cans equal to each of the cans
designated in Column 1.
