It's do to with rounding from the conversion rates between power of 2 and power of 10 conversions e.g. mb to gb

To a hard disk manufacturer, one KB is 1000 bytes, one MB is 1000 KB, and one GB is 1000 MB. Essentially, if a hard disk is advertised as 500GB, it contains 500 * 1000 * 1000 * 1000 = 500,000,000,000 bytes of space. The hard disk manufacturer thus advertises the disk as a 500 GB hard disk.

However, manufacturers of RAM don’t sell it in even groups of 1000 – they use groups of 1024. When you’re buying memory, a KB is 1024 bytes, a MB is 1024 KB, and a GB is 1024 MB. To work back from the 500,000,000,000 bytes above:

500,000,000,000 / (1024*1024*1024) = 465.66 GB

also on top of this, there's formatting so you lose even more space.

In response to OP, they want at least 16gb free space on a USB, so you need a 32gb usb. It's counter-intuitive I know

>says it needs 16gb
>buys a 16gb stick

This is all your fault OP

So buy a 32 GB, they can go as low as 5-7 USD.
Use 16 GB drive for Linux Live o save your maymay pictures.

is already pointing in the right direction.
when using the (correct) SI prefixes (k, M, G, ...), the following equalities obtain:
1 kB = 10^3 bytes = 1,000 bytes
1 MB = 10^6 bytes = 1,000,000 bytes
1 GB = 10^9 bytes = 1,000,000,000 bytes
however, since an amount of binary information is more sensibly summed up in powers of 2 (rather than in powers of 10), there also exist IEC prefixes, which are derived from the SI ones:
kilo (k) ≙ Kibi (Ki)
Mega (M) ≙ Mebi (Mi)
Giga (G) ≙ Gibi (Gi)
1 KiB = 1 Kibibyte = 2^10 bytes = 1,024 bytes
1 MiB = 1 Mebibyte = 2^20 bytes = 1,024^2 bytes = 1,048,576 bytes
1 GiB = 1 Gibibyte = 2^30 bytes = 1,024^3 bytes = 1,073,741,824 bytes

to make matters worse, Windows (at least according to this: https://de.wikipedia.org/wiki/Byte#Vergleich) uses the SI prefixes, while the acutal numbers reported are those of the IEC ones, i.e., if Windows says 16 GB (= 16,000,000,000 bytes) it actually means 16 GiB (= 16 * 2^30 bytes = 17,179,869,184 bytes). So while you’re memory stick might not be actually 16 GiB large, it still is most certainly larger than 14.59 GB.

apparently, somebody already sued Wester Digital over this issue:
