TSRGD was changed updated last year, I think, maybe it was two yeas ago, so that metric and imperial can by placed on one sign rather than requiring two separate signs.
In general, TSRGD requires imperial units and only allows yards and miles for distance:
http://www.legislation.gov.uk/uksi/2016 ... art/3/madeThis is overridden for some signs, including height and width restrictions, and yes, it allows them on the same sign now, with the more widespread metric in brackets (thank you David Cameron and your petty little Englander point-scoring(!)).
The blue rectangle is not a sign where is overridden, so one could argue that the distance should be given in yards, to the nearest 10 yards (thank you David Cameron and your petty outlawing of Norfolk traditions(!)), which would mean it should read "0 yds".
Fortunately, any art is allowed on a blue rectangle information sign, so one can also argue that 1.5m is part of an artwork and, ultimately, the sign is only information and not required to outlaw careless driving.
