These are likely US tons, so 2722kg. I'm not sure about the SI conversion of the semitractor-trailer units.
> scientists expect the object to carve out a hole 33 feet to 66 feet across
Oh, so 10-20 meters :-)
I loled at this. It was so obviously 10 - 20 meters.
Should probably just say "About 50 feet in size"
Earlier reports put the mass at explicitly "4 metric tons" [0][1], so it is a bit of a guess either way.

Are we talking Arizona trailers, normal NA trailers or international-compliant sizes to begin with?
