Apparently Gizmodo-Australia has failed to note that Australia is metric: "A built-in thermometer lets the insulated mug report back how hot or cold its contents are via a two-digit LCD display on the outside. But if you can’t make hide nor hare of the metric system mumbo jumbo it uses to display the temperature, the mug also has a heart on its side that glows blue, orange or red, visually indicating how hot or cold your beverage is." http://www.gizmodo.com.au/2013/06/why-havent-mugs-told-us-the-coffees-temperature-until-now/ US "news" organizations should be aware that the rest of the world uses metric in everyday life and mocking the metric system makes them look the fool, not the metric system. Perhaps it could be an AP guideline. (I'm pretty sure they just "borrowed" an item from the US version of Gizmodo)
