Kibibytes and kilobytes

IEC standard for base-2 units:

* 1 KiB (kibibyte) = 1,024 bytes (Note: big k)
* 1 MiB (mebibyte) = 1,024 KiB = 1,048,576 bytes
* 1 GiB (gibibyte) = 1,024 MiB = 1,048,576 KiB = 1,073,741,824 bytes
* 1 TiB (tebibyte) = 1,024 GiB = 1,048,576 MiB = 1,073,741,824 KiB = 1,099,511,627,776 bytes

 

SI standard for base-10 units:

* 1 kB (kilobyte) = 1,000 bytes (Note: small k)
* 1 MB (megabyte) = 1,000 kB = 1,000,000 bytes
* 1 GB (gigabyte) = 1,000 MB = 1,000,000 kB = 1,000,000,000 bytes
* 1 TB (terabyte) = 1,000 GB = 1,000,000 MB = 1,000,000,000 kB = 1,000,000,000,000 bytes

 

It is not allowed to use the SI standard for base-2 units:

* 1 kB ≠ 1,024 bytes
* KB (with a big k) does not exist
