Handy Metric Conversions
I hate conversions. I never know what to multiply by what to get the other. Anyways, luckily I found this to clear everything up.
Metric Conversions

We Americans (defined as residents of the USA) frequently have problems with metric conversions. In an attempt to clarify the conversion process here are some common conversions.

1 million microphones = 1 megaphone
2000 mockingbirds = two kilomockingbirds
10 cards = 1 decacards
1 millionth of a fish = 1 microfiche
453.6 graham crackers = 1 pound cake
1 trillion pins = 1 terrapin
10 rations = 1 decoration
100 rations = 1 C-ration
10 millipedes = 1 centipede
3 1/3 tridents = 1 decadent
2 monograms = 1 diagram
8 nickels = 2 paradigms
2 wharves = 1 paradox
