What it does

The Data Unit Converter translates a digital storage amount between bytes, kilobytes, megabytes, gigabytes, and terabytes - entirely in your browser. Pick a convention and the tool shows your value in every unit at once: decimal (B, KB, MB, GB, TB - each step ×1000, the SI standard storage makers use) or binary (B, KiB, MiB, GiB, TiB - each step ×1024, the IEC standard operating systems report). Everything runs 100% client-side, so nothing you enter leaves your device.

It also settles the perennial “why does my 500 GB drive show up as 465 GB?” question: the drive is sold in decimal GB (×1000) but reported by the OS in binary GiB (×1024) - the same bytes, two naming conventions. Read the byte value from the decimal table, switch to binary mode, and the table shows the matching GiB figure.

How to use it

1. Pick a base at the top: Decimal · 1000 (KB/MB/GB/TB) or Binary · 1024 (KiB/MiB/GiB/TiB).
2. Enter the Value you want to convert.
3. Choose the from unit (left control) and the to unit (right), or tap the swap arrow to flip them. The large Result shows the focused from → to conversion.
4. Glance at Value in all units to see the amount in every unit of the current base at once - each row has its own Copy button.
5. Use Copy share link to send the exact view to someone.

Examples

Decimal - gigabytes to megabytes (the default view)

1 GB → 1,000 MB (base 1000)

Binary - mebibytes to bytes (the “real” size)

1 MiB → 1,048,576 B (base 1024)

The all-units table (enter 1 GB, base 1000)

B    1,000,000,000
KB   1,000,000
MB   1,000
GB   1            (input)
TB   0.001

Good to know

• Two conventions: KB/MB/GB/TB use ×1000 (decimal, SI); KiB/MiB/GiB/TiB use ×1024 (binary, IEC). Switching the base remaps your selected units to the equivalent rank automatically (e.g. MB → MiB).
• Cross-base comparison: the tool converts within one base at a time. To compare a decimal figure with a binary one, read its byte value from the table in decimal mode, then switch to binary mode and enter that byte value.
• Shareable: your value and unit choices are encoded in the URL (?base=…&v=…&from=…&to=…), so a link reproduces the exact view.
• Private: all math runs locally - safe for any input.
