You can't halve the temperature of something by halving its measument in Celcius, because the celcius starts at some arbitary point above absolute zero.

50 degrees celcius is 86% as hot as the boiling point of water, not 50%.

You both did the math in kelvin then converted to C. You knew what you were doing.
