Okay guys, hear me out:
What if Ameribraps converted to using metric for physical measurements, but the rest of the world joined us in our use of Fahrenheit for temperature? Fahrenheit degrees are smaller and thus negate the need for decimals (the 0°C freezing / 100°C boiling thing is pretty much only good for convenience anyway), and most burgers don't know all their imperial conversions even well into adulthood; metric is clearly superior in this way.
