In formal writing I like to do this (in British style):
The infant weighed 10lb 5oz;
a 10lb 5oz infant
He was 6ft 3in tall;
a 6ft 3in man
My question is about the plural usage: do we have to change
The infant weighed 10lb 5oz.
The infant weighed 10lbs 5ozs.
I say no, but I’m really just reaching out for confirmation here.
Also, would you use my examples — with abbreviations for pounds, ounces, feet, and inches — in formal writing?
If not, how would you write it?
