It's way past fridge, and into the serious (deep) freezer range. Our home freezer is set to -18 °C which would be 255 Kelvin). Around 45 Kelvin away from room temperature, I'd say without looking up the formal definition.

But at normal atmospheric pressures.

An improvement to the alternative which was in the realm of what, a few kelvins or something?

afaik -150f or at room temperature at millions of earth pressure

If we count my garage as a room, then it's room temperature every winter.
