Storage Disk manufacturers calculate as 1 GB = 1000 MB, 1 MB = 1000 KB, 1 KB = 1000 Bytes.
Actually , Operating System and Software applications calculate as 1 GB = 1024 MB, 1 MB = 1024 KB, 1 KB = 1024 Bytes.
Hence, 16 GB = 16,00,00,00,000 bytes (according to manufacturer)
To calculate for Software system specification,
[16,00,00,00,000/(1024 x 1024 x 1024)] = 14.90116119384766 GB
So, 16 GB pen drive shows 14.9 GB approximately.
