tonne vs ton
I’m all for the metric system, and I’m sure a lot of British schoolchildren would be well pissed off if UKIP’s idea of restoring the imperial system ever came to fruition. But I do find sentences like this, in a item on the BBC website, rather strange and unnatural:
Mr Teller says the first question is not “How can we make a tonne of money?”
I know that tonne is our unit of measurement now, but does it have to take over our idioms as well, especially as this is probably more of an American idiom anyway (I think we Brits would be more likely to say ‘ton(ne)s of money’)?
The following idioms are all listed in British dictionaries with ‘ton’ or ‘tons’:
They came down on him like a ton of bricks.
That bag of yours weighs a ton!
I’ve got tons of work to do.
We’ve got tons of food left over from the party.
I don’t know why the BBC insist on using tonne in idioms. Perhaps they think young people won’t know what a ton is. I say keep the idiomatic ton, and leave tonne for weights. After all people don’t say they’re off to spend a new penny, do they? (Actually I’m not sure anyone says that anymore anyway!)
