The United States post office must use the most sensitive scale in the world.
I thought that a package I mailed weighed 13 pounds. I was mistaken. It only weighed 10 pounds and 4.960000000000008 ounces.
Does that equal eight trillionth of an ounce, or 800 quadrillionth? A pico ounce or a femto ounce?

I saw this composition book for sale for $8.00. Crazy right? Except this chart really does happen to have Useful Information. It has fractions (and decimals and percents). And temperature conversion. And is written in clear English. For example, under Metric Unit Conversion, the column reads “When You Know: ________ Multiply By: ________ To Find: ________”.
What I do not see are roods (square measure), scruples (Apothecaries’ weight), reams (paper measure), grains (troy weight), or knots (miscellaneous measures). It is also the only chart to include “mass.”

This Useful Information chart is on the inside back cover of a graph paper composition notebook. The cover is not the typical marble design. Right away I see some cool icons and graphics…the other Useful Information charts 1-3 have only text. Also, this one has a 3-inch ruler! The content is much the same as chart 2.

This is the inside back cover of the composition book. There is another Useful Information chart on the outside cover of this notebook, with different information. It appears as if it was written by a different author.

This chart is on the outside back cover. What is interesting is that the book has another Useful Information chart on the inside back cover, just in case one wasn’t enough. I would guess that about 90% of the information is the same in both charts, though there are differences. You may notice that there are no metric-to-metric or metric-to-U.S. standard conversion tables.
