Adam is missing the negative sign. 4 Kelvin (which is the same scale, different baseline as Celsius) is -452 degrees F. It's cold. Really, really cold. It also usually requires the use of a lot of liquid helium, which is a finite resource, growing increasingly scarce and increasingly expensive to purchase.

Might there be a missing word?
My physics is a little rusty but do you need a "below" in there? :-)
"...absolute zero - which is roughly 460 degrees F..."
