Hi, my name's Julia, and today I'm going to show you how to go from Celsuis to Kelvin with uncertainties. Let's start with just going from Celsius to Kelvin, and we'll worry about uncertainties at the end of this. The equation we're going to use is Kelvin equals whatever our degree Celsius is, plus 273.15. So, for example, let's start - let's try room temperature, which is about 23 degrees Celsius. The Kelvin temperature, Kelvin room temperature is, we're going to but 23 in, because that's the degrees Celsius we have, and we're going to add 273.15 and that is, let's add. We got 273.15, 23, 5, 1, 6, 9, 2. So, the answer is 296.15 Kelvin. Now the difference between the Kelvin scale and the Celsius scale is that they start at difference null points, but as you increase for every Kelvin, you increase the same amount with the degree of Celsius. I'll say that again. The magnitude of one Kelvin is equal to that of one degree Celsius, so if you want to figure out what the uncertainty is, it's the same. If you have an uncertainty of, say, plus or minus a degree Celsius, say 1 degree Celsius, that is going to be equivalent to plus or minus 1 Kelvin. So if we had our room temperature at 23 degrees plus or minus 1 Celsius, in Kelvin we're going to have 296.15 plus or minus 1 Kelvin. So that's how you go from Celsius to Kelvin with uncertainties. Thanks for watching.
