Here it is:
# sg_readcap -l /dev/sdc
Read Capacity results:
Protection: prot_en=0, p_type=0, p_i_exponent=0
Logical block provisioning: lbpme=0, lbprz=0
Last LBA=3907029167 (0xe8e088af), Number of logical blocks=3907029168
Logical block length=512 bytes
Logical blocks per physical block exponent=0
Lowest aligned LBA=0
Hence:
Device size: 2000398934016 bytes, 1907729.1 MiB, 2000.40 GB, 2.00 TB
