Your basic reference is wrong. The Weights and Measures Act 1948 [not
"of 1948"] defined the yard to be 3600/3937 of the metre, whose
definition I forget. The 1963 [?, I thought it was 1967] Act redefined
it to 0.9144 metres, and defined the metre using the same wording as the
SI definition. Later Acts have kept the definition of the metre in step
with SI.
