It may or may not be considered a sland term, but it is not to distinguish it from the tonne; the two are synonymous. > The original UK tonne of 2200 (998 kg) pound was redefined under the WMA to > be now 1000 kg.

The 'original' UK ton (not 'tonne') was 20 x 112 lb= 2240 lb. It has never been 're-defined'. It is simply no longer used. The only legal 'ton' is the tonne. -- Chris KEENAN UK Metric Assoc: www.metric.org.uk
