3. If we were re-doing the metric system the nanosecond would be a useful measure of distance.

The nanosecond seems more rational and scientific than the meter, which was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole, a measurement that turned out to be a little off, so they made a bar of platinum, put it in icewater and said here, there's your meter. (And it was handy to use that same icewater as the measure of zero degrees Celsius.)

A nanosecond is 11.8 inches.

A U.S. American football field might be 300 nanometers long, which is a little over 98% of 100 yards. Instead of a fifty yard line, you'd have a 150 nanosecond line.
