236.588 is not a design target. It is eight ounces.

The capacity figure on this shelf is a milliliter number with three decimals

236.588. 118.294. 473.176. 354.882. Which look like measurements and are not: they are the output of an arithmetic operation.

The unit the container was actually specified in is recorded separately

And for 215 of this group’s 238 containers that unit is the fluid ounce. Twenty one rows are milliliters and two are cubic centimeters.

So the conversions are readable straight off the list

One ounce becomes 29.573 milliliters. Two becomes 59.147. Four becomes 118.294. Eight becomes 236.588. Twelve becomes 354.882. Sixteen becomes 473.176.

And the commonest sizes are the commonest ounces

47 rows at eight ounces, 44 at four, 31 at sixteen, 29 at two, 19 at twelve, 17 at six, 8 at three and 6 at nine. That is 201 of the 215.

The remaining fourteen ounce rows are oddments

Single rows at three quarters of an ounce, one and a quarter, one and a half, two point two, eight point four, eight point nine, fourteen and fourteen and a half, plus two at ten.

The twenty three native rows are the only round numbers on the shelf

15, 30, 50, 55, 75, 100, 125, 150, 200, 250 and 500 milliliters, one or two rows each. Which means the figures a buyer would think in belong to a small minority of the shelf.

And two of those twenty three are recorded in cubic centimeters

A third unit string for the same physical quantity. Cubic centimeters and milliliters are the same thing, which makes this a vocabulary difference rather than a conversion, but it is a third string all the same.

The precision is also an artifact and worth not over-reading

Eight fluid ounces is 236.5882 milliliters and the column stores 236.588. Three decimals of a converted figure is not three decimals of a measurement, and no page here treats it as one.

Which is the same observation the spine makes about its own test

The article definition cannot be answered from the object; you need to know the downstream use. The capacity figure cannot be interpreted from the number; you need to know which system it came from.

In both cases the record is complete and the answer is elsewhere

Nothing is missing from the capacity column. It is simply not the field that tells you what you need, and the next page is about what that costs a buyer.

The Davis Pack Supply catalog, measured 19 October 2026. Of this group’s 238 containers, the recorded capacity string is in fluid ounces for 215, in milliliters for 21 and in cubic centimeters for 2. The milliliter figure stored alongside it is arithmetic performed on that string: 1 oz becomes 29.573 mL on 4 rows, 2 oz becomes 59.147 on 29, 3 oz becomes 88.721 on 8, 4 oz becomes 118.294 on 44, 6 oz becomes 177.441 on 17, 8 oz becomes 236.588 on 47, 9 oz becomes 266.161 on 6, 12 oz becomes 354.882 on 19 and 16 oz becomes 473.176 on 31, with single rows at 0.75, 1.25, 1.5, 2.2, 8.4, 8.9, 10, 14 and 14.5 ounces. The 23 rows recorded natively carry 15, 30, 50, 55, 75, 100, 125, 150, 200, 250 and 500 milliliters, one or two rows each. There are 29 distinct capacity values across the 238 containers.

Written from 29 CFR 1910.1200 and from the catalog as it stood on 19 October 2026. That section is the Hazard Communication Standard and it governs the classification and labeling of hazardous chemicals in the workplace; it does not govern bits, blades, wheels or collets, and nothing here says it does. Nothing here determines whether any item is an article under paragraph (c), because that turns on a particular use. No container on this shelf is described as rated for any chemical, fluid or dust, and nothing here is guidance about handling a tool, about dust exposure, about ventilation or about protective equipment. This shelf is a subset of the store-small-dry shelf and the sewing notions property enumerates that shelf.
