In the cases where you need to go over 99F, Fahrenheit does not need a full digit. You only need two thin segments for the "1." Or you can double it up with the negative sign. It's big enough of a deal that most appliances don't include the extra digit. Whether it be for design aesthetics or additional manufacturing cost. It's big enough of a deal that the article's author complained about not being able to set their thermostat to a comfortable level. > I started writing this because of a thermostat in Australia that didn’t use decimal points in Celsius. It was never a comfortable temperature inside. And 0.5C may not seem like a big difference, but if people could comfortably set their appliances 0.5C degrees lower it could save a lot of energy.
