The UK: not a metric market in practice

The United Kingdom runs on the imperial system for everyday quantities while its law is metric. Net-content declarations, serving sizes, storage instructions and every dimension on a pack artwork have to be produced for this market rather than translated into it.

A metric-only artwork pipeline needs a second set of plates for this market, not a second language.

Constraint

Held since January 1, 2010A rule, law or policy that limits what you may do or say. The earliest date we are willing to say this held. It may well have been true before that; we do not backdate a record past the evidence we have read. Supported, version 1.

This entry is wrong if

The current Unicode CLDR release records the United Kingdom as a metric market for everyday measurement, or the market’s weights-and-measures law stops permitting non-metric declarations on consumer packaging.

Written before the record was published, not after. If you can show this, send it to hello@tryorbt.com and the correction goes on the record with the entry.
