Digging a little deeper... (0 degrees Celsius) + (0 degrees Celsius) - (0 degrees Celsius) = 0 degrees Celsius (0 degrees Celsius) - (0 degrees Celsius) = 0 kelvin (0 degrees Celsius) + (0 kelvin) = 0 degrees Celsius The last 2 of the 3 are wrong, so I'd say this is definitley a bug. EDIT: I think I figured it out. It's converting everything after the first temperature to Kelvin, without converting the first temp to Kelvin, and then just doing the arithmetic on the numbers... 0C + 0C => 0C + 273K => 0 + 273 = 273 0C + 0C - 0C => 0 + 273 - 273 = 0 0C - 0C => 0 - 273 = -273 = 0K (ok, weird this one then converts back to K) 0C + 0K => 0 + 0 = 0 EDIT 2: While this does match the results seen by google, I think _delirium's solution is more likely the reason.

0C - 0C => 0 - 273 = -273 = 0K (ok, weird this one then converts back to K) Your math/logic is wrong, (A - A) => (B - A) you converted 0C to both 0 and 273. Convert everything to Kelvin and it all makes sense. It's non-intuitive because 0C indicates a positive amount of energy rather than no energy as 0K does.

  If you read my comment leading up to that, you'd see why I did it that way. But I agree with the other comment that it's more likely Google is just converting everything to Kelvin as it's canonical calculating form.

No. It's converting EVERYTHING to K, then doing the arithmetic, then converting the result to C. 0C + 0C = 273K + 273K = 546K = 273C 0C + 0C - 0C = 273K + 273K - 273K = 273K = 0C 0C - 0C => 273K - 273K = 0K 0C + 0K = 273K + 0K = 273K = 0C

Yup you guys are right. This is what I get for trying to overanalyze a problem at 3am.
