 So let's do this one backwards essentially from the the last time we did I guess not the same numbers But remember how do we convert kelvin to Celsius now, so remember the conversion? It was adding 273.15 when you add Celsius, so it's going to be subtracting 273.15 Because that's the difference between the freezing point of water and absolute zero, right? So minus 273.15 I'm not going to do that in my head Okay, so what did I get? 228 degrees Celsius So can we use all of those numbers? No because we'd be telling ourselves or telling whoever that we were Having a more precise answer than what was measured. So this was measured to Zero digits after the decimal place. So this one has to do two. So what's the last one? It's an eight. So we're going to round the next number up. So our answer that we'll present is 229 degrees So after the last few problems that one should I'm not going to
