Units are regulated by the International Bureau of Weights and Measures. It determines the absolute value of a kilo as the thousandfold value of its original value. In IT a kilo always means 1,024, therefore, in 2000 the International Bureau of Weights and Measures determined that 1,000 Bytes are a Kilobyte (KB). As a result, whenever 1,024 Bytes are meant, then the unit Kibibyte (KiB) should be used.
Windows claims to measure Gigabyte (GB), but actually means Gibibyte (GiB),
