Shopping for groceries outside of the U.S. is so straight-forward, the U.S. food industry should worry about loss of profits in moving to metric.
Imperial:
$4.49 / lb
0.67 lbs
≈ ???
Metric:
$9.89 / kg
$0.3 kg
≈ $3.00

Similarly, I wouldn't expect you to buy 0.67 kg of food priced by weight outside of the US.
I meant to say that in the U.S. things are marked in ounces. So, it's like calculating (10 oz / 16 oz.) * price. Whereas, elsewhere it's usually 100 grams.
