![]() ![]() Temperature is an intensive quantity and describes the energy state of the matter. Temperature and temperature units What is temperature? So, we can round it up by saying 100 ☏ equals 37.8 ☌.In practice, this is easiest to do by first adding 10 % and then adding another 1 %. If we want to make it more precise (and we always do!), we can add 11% instead of 10%. But we can get pretty close if we divide it by 2 and then add 10 % (to be exact we should add 11.11 %). What? Ok, this is maybe too difficult, as 5/9 is 0.555555. Step 1: Remove 32 ☏ from the ☏ temperature. How to convert a Fahrenheit temperature to Celsius temperature in your head? Sure it gives you a rough value, but as you can see the result will be a bit too high. For the above example of 20 ☌, this would give 20 x 2 + 32 = 72 ☏. But that will give a bit too high results, so take the end results down a bit. The “ quick and dirty” way would be just to multiply the Celsius reading by 2 and add 32 ☏. Step 2: You need to remember that 0 ☌ equals 32 ☏, remember that! So, finally, ad that 32 ☏ offset to the result. Yep, I know that multiplying with 1.8 in your head is not that easy, but there is a pretty easy way around this: multiply the ☌ reading first with 2 (easy) and then take off 10% (also easy). (Or it is 9/5, but I think 1.8 is easier to think). Don’t worry, this conversion is not that complicated, let me explain to you how to do that quickly in your head. Sometimes you see a Celsius temperature and you don’t always have a unit converter quickly available. How to easily convert a Celsius temperature into Fahrenheit temperature in your head?
