The URSA has a 3K Anamorphic mode that records 3072x2560. It does a 6:5 crop of the sensor using a 16.9mm (w) x 14.08mm (h) window of the sensor. Once you desqueeze it, you have 6144x2560, which is the 2.4:1 aspect ratio.
The full URSA 4.6K sensor area is 25.34x14.25mm.
The crop of the 3K anamorphic window of the sensor is (3072/4608) .66667.
The conversion from the full width of the URSA 4.6K sensor to full frame is (25.34/36) 1.42.
The conversion from the full width of the URSA 4.6K sensor to full frame is (1.42/.66667 =) 2.13 FF crop for 3K.
For more information:
"Wouldn't a 32mm 2.0x anamorphic lens on an URSA 4.6K G2 at the 3K anamorphic sensor area be a 48mm (32/.66667) Super 35 equivalent or a (32 x 2.13) 68mm FF equivalent lens?"

You would have twice the equivalent focal length in terms of the width displayed after desqueezing.
