The last couple of years we have had between -36 F to 97 F. Or -38 to +36 C. I like to be able to tell when the roads might get slippery (below +3 C or so), when the car will get problems starting if you forgot to plug in the heater (about -25 C), When it's time for the shorts (+18 C?). Also handy to know that I need 3-6-3 ammounts to make pancakes. 3 eggs, 6 litres of milk and 3 dl flour (that will be meassured with grams because easier, can just pour everything into the bucket and press "tara"). Flour weighs 60 g per dl. Put bowl on scale, start it. Pour flour in the bowl until it reads 180 g. Reset and pour in milk until it says 300 g. Mix until perfect. Add eggs. Reset scale and pour another 300 g and mix again. Start frying!
