decimal day

On this day in 1971, the United Kingdom and Republic of Ireland decimalised (see previously) their respective pounds and pence (d., from Latin for denarii), abolishing shilling (s., from Latin solidi) and subdividing the pound (£, pondo librae) into one hundred new pence (p). A substantial publicity campaign championed by the Decimal Association that also helped make the transition into the metric system made the change-over a relatively smooth one.
