With
modern man now using the metric system there is sometimes a need to
remember what the old units of measurement were, the common and not
so common.
The UK table should really be the English table as some very old measurements
were slightly different in Scotland, Ireland or Wales.
The metric conversions shown are approximate, see the main
tables for accurate factors.
