A comprehensive data storage converter that shows conversions across all unit standards simultaneously. Supports 23 units spanning Bits & Networking (bit, nibble, kilobit, megabit, gigabit, terabit - SI powers of 10 used by ISPs), SI Decimal Storage (byte, KB, MB, GB, TB, PB, EB - powers of 10, used by drive manufacturers and macOS), IEC Binary Storage (KiB, MiB, GiB, TiB, PiB, EiB - powers of 1024, used by Windows, Linux, and RAM specs), and Extreme Scale (zettabyte, yottabyte, zebibyte, yobibyte). Finally understand why a 1 TB drive shows up as ~931 GiB in Windows. Type a value, pick a unit, and instantly see every other unit's equivalent. Click any result row to use that value as the new input for reverse conversions. Adjust significant figures (3–12) and toggle scientific notation for extremely large or small values. Includes a collapsible quick-reference table. 100% browser-based - no data leaves your device.
How to Use
- 1Type a number in the input field at the top
- 2Select your starting unit from the From dropdown (e.g. Gigabyte, Megabyte, Gigabit)
- 3Select your target unit from the To dropdown - the result appears instantly
- 4All 23 conversions appear simultaneously, grouped by standard: Bits & Networking, SI Decimal, IEC Binary, and Extreme Scale
- 5Hover any result row to reveal the copy and swap buttons
- 6Click the copy icon to copy a value to your clipboard
- 7Click the swap icon (⇅) on any row to use that unit as the new input and reverse the conversion
- 8Adjust 'Sig. figures' to control result precision (3 to 12 significant digits)
- 9Toggle 'Sci notation' to display very large or very small values in exponential form
- 10Collapse a unit group by clicking its header to reduce clutter
- 11Open 'Common conversions' at the bottom for a quick reference table
