 So I know I've already told you that I don't want you to memorize too much in this class, but unfortunately this is one of the things you're going to have to memorize. Like we said before is the formula from going from Celsius to Fahrenheit and from Fahrenheit to Celsius back and forth, right? So remember the formula is degrees Fahrenheit equals 1.8 times the temperature in degrees Celsius plus 32. Let's do this. So we got this temperature in degrees Celsius, so we want to do the temperature in degrees Fahrenheit. So all we got to do is use that formula, 1.8 times 75.032. If you want to, I just like to convert the units just straight away so you don't have to go through a unit conversion process. It's kind of annoying. Since this is one of the first things you're doing. But anyway, so then just plug it in. So 1.8 times 75 plus 32, that gives you 167 degrees Fahrenheit. So that's cool that there's three sig figs here because you need three sig figs here. So that's that. So we'll do a conversion from Fahrenheit to Celsius in a second and then you'll get the other formula. In fact, it's just the inverse of that one as you can imagine. So we'll show how to calculate it and then do the next problem.
