It's just units; the G in lvm's output signifies powers-of-two units,
wheras the GB reported by fdisk is in powers-of-ten (SI units).
See the lvm man pages for a description of the units supported (lower
case are SI, upper case are powers-of-two).
Strictly speaking, the powers-of-two versions should use the SI binary
prefixes (MiB, GiB, etc.):
