Yeah, I always found this to be an utterly strange convention. Do you say, "that'll be dollars one hundred", when you tell someone a price? Would you write, "I'm lbs200"?

I suppose it does give away the cultural difference, but this is one where the Indians (and a lot of others) get it right.

$566 is right. SI and everything else got it wrong. Most significant figures should come first. Unit is the most significant figure.

"Five hundred...." is meaningless. "dollars five hundred..." is a useful preliminary approximation.

When I think about it, I have to agree.

It would make for a fast mental shortcut in preparation. For example: you need to move an item. How much does it weigh?

Grams… ok, pocket

Kilograms… might need to put it in the trunk.
