From the BBC website:

"The BBC Weather Centre said visibility had dropped to 50m (164ft) in
places."

Of course nobody had said 164 feet. 50 metres is clearly a round
figure and should have been converted (why that is deemed necessary
beats me) to a round figure, eg 50 yards. "The Times" and the media
in general don't seem to grasp the concept that you should not convert
approximate figures into apparently accurate figures in different
units. Only last week, The Times had an article about sail powered
ships with the kite flying at heights of "up to 300 metres (984
feet)".

Surely these writers - or sub editors - had to pass GCSE maths?
Conversion and rounding is in the curriculum.
