"Useful Metric Conversions" joke

We Americans (defined as residents of the USA) frequently have problems with metric conversions. In an attempt to clarify the conversion process I now submit some "Useful Metric Conversions."
1 million microphones1 megaphone
2000 mockingbirdstwo kilomockingbirds
10 cards1 decacards
1 millionth of a fish1 microfiche
453.6 graham crackers1 pound cake
1 trillion pins1 terrapin
10 rations1 decoration
100 rations1 C-ration
10 millipedes1 centipede
3 1/3 tridents1 decadent
2 monograms1 diagram
8 nickels2 paradigms
2 wharves1 paradox
I hope this proves a useful tool.
