If the metric system did ever take over, we'd have to change our thinking to the following:

• A miss is as good as 1.1 kilometers.
• Put your best 0.3 of a meter forward.
• Spare the 5.03 meters and spoil the child.
• Twenty-eight grams of prevention is worth 453 grams of cure.
• Give a man 2.5 centimeters and he'll take 1.06 kilometers.
• Peter Piper picked 8.8 liters of pickled peppers.
