I bought a metric conversion calculator at Radio Shack not long ago. Great
buy for under $20.00! It has "20 instant converstions between U.S. and
Metric Measurements." It is a Radio Shack brand and is about 4.5" x 2/5" in
size. It is solar powered. My last one lasted over 20 years and I bought
this new one only a month or so ago.
