Pip,

Regarding your statement of April 8th @ 11:06 p.m.

"For example, the improved pint is 34.700000 cu.in."

If you ever do come back to Planet Earth, try measuring its' circumference again.

But before you do, you must prepare yourself for stunning relavations. One of those that you might come across is that the improved pint measures out as:

1 imp.pt. = 34.560000 cu.in.

To make your landing on Planet Earth as safe as possible, consult:

"If you ever do come back to Planet Earth"

I didn't expect that you would, but clearly I was wrong.
