The unexpected ability of an American to convert easily between grams and ounces. Often derived from college experiences dividing marijuana and other substances.
We needed to know how many grams were in 2 ounces of sugar. Thankfully my <i>drug math</i> skills kicked in and told me it was 28.5 grams x 2. Now if only I knew drug arithmetic.
