its always an achievement to get colder than previously but why isnt there another unit to measure the approach to absolute zero?

It all depends on what you use as a reference for 0. In Celsius that's the point for water turning to ice which was the established 0 point from before there was a concept of absolute 0. That's -273.15 degrees Celsius away from absolute 0. When the concept of absolute 0 developed a new unit of measure was developed called kelvin.

even with kelvin it becomes an exponential function the closer to zero it is so to even use that near the end is meaningless i was more asking why an exponential unit hadnt been created for temperature
