GUI showing LVs 7% bigger size

[moxfan]

Actual LV sizes:

root@pmx8:~# lvs -a vg-b | grep pthin | grep rimage
  [pthin_tdata_rimage_0]                 vg-b iwi-aor--- 99.99g
  [pthin_tdata_rimage_1]                 vg-b iwi-aor--- 99.99g
  [pthin_tmeta_rimage_0]                 vg-b iwi-aor---  1.00g
  [pthin_tmeta_rimage_1]                 vg-b iwi-aor---  1.00g

As the attached image shows, in the GUI the 'pthin' logical volume's data and metadata space are being quoted 7% larger than their actual size: 107 GB instead of 100 GB and 1.07 GB instead of 1 GB. Not sure why. Has anyone seen this phenomenon before?

I assume this difference comes down to lvs measuring size in GiB while in the GUI, it is reported in GB (1GiB = 1.074GB).
