Adjusting to life in the U.S. comes with a whole bunch of new things to get used to. One that can really trip you up is the imperial system of units. Sure, you might quickly catch on that an inch is about the same as 2.5 centimeters, or that three feet make up nearly a meter. But temperature, that's a whole different ball game.
Unlike other measurements, there's no simple multiplier, and the point where you start counting is different too. Want to chat about the weather? You're going to need to do some quick math in your head, and this comes in handy in other social situations too. That's why a temperature widget on your home screen that lets you talk both Celsius and Fahrenheit is a total game changer.
