How it is calculated
The value is converted to bytes first. Decimal units use powers of 1000, while binary units such as KiB, MiB and GiB use powers of 1024.
Convert decimal and binary data units with a clear tool for files, disks, memory and network notes.
The value is converted to bytes first. Decimal units use powers of 1000, while binary units such as KiB, MiB and GiB use powers of 1024.
KB means 1000 bytes in decimal notation. KiB means 1024 bytes in binary notation.
No. One byte equals 8 bits, so 8 bit converts to 1 B.
Before comparing a download, disk label or memory figure, preserve the exact unit symbol. MB and MiB are different choices, and a lowercase b is not a byte. This tool changes the unit of a quantity; it does not inspect a drive, account for filesystem overhead or estimate compression. If a supplier writes only megabytes without defining the convention, ask for the byte count rather than treating the discrepancy as lost storage.
Take a synthetic file containing 1,500,000 bytes. Dividing by 1,000,000 gives 1.5 MB; dividing by 1,048,576 gives about 1.430511 MiB. Both describe the same file. Use bytes as the intermediate check, then reverse the conversion. For a batch of ten identical files, multiply the original byte count by ten before converting, instead of summing ten separately rounded display values.
Display precision is not evidence of available disk space. A storage amount is also not a transfer rate: MB does not become seconds without a speed and consistent time units. Keep protocol overhead, usable capacity and redundancy outside this numerical conversion. For a report, write the chosen decimal or binary convention next to the result so readers do not compare different definitions under the same label.
