Quiz Description

Questions in this quiz will require you to recognize that we measure things with way too many different units, and many of them require you to make a conversion from one unit to another. And now for a readin' of the rules, here's Bruce:

1. Pencil and paper allowed for computation, but no calculators.

2. If there is a * at the end of the question, an exact answer is required (and it will be an integer). Otherwise, answers within 3 percent of the given answer will be counted as correct.

3. For computation questions, simple numbers as answers will suffice (i.e., you don't have to put the converted units).

So, yeah...have fun.

One neat fact (among many) I learned from xkcd's "What If?" is that gas mileage ultimately has units of inverse area (i.e., 1/length^2). This means a fuel economy of 20 miles per gallon is equivalent to how many inverse square feet (1/ft^2)?
