Data Storage Unit Converter

This data storage unit converter lets you instantly switch between bit, byte, kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), and petabyte (PB) using precise binary (base-1024) arithmetic. Whether you are checking a hard drive's real capacity, estimating cloud storage needs, or debugging file size limits in code, you get accurate results in real time. No sign-up, no installation — just fast, reliable conversions.

Benefits

Manual storage conversions are surprisingly error-prone because the multiplier shifts at every step. This tool removes the guesswork entirely:

  • Binary-accurate: Calculations follow the IEC standard (1 KB = 1,024 bytes), matching what your operating system actually reports.
  • Instant results: Values update as you type — no need to press a calculate button.
  • All units at once: See every unit from bit to PB simultaneously for easy comparison.
  • Zero friction: No ads, no rate limits, no account needed.

Use cases

  • Reconciling the advertised capacity of an SSD or HDD (decimal GB) with what Windows or macOS reports (binary GiB).
  • Planning backup storage on Google Drive, Dropbox, or any other cloud service when your data size is quoted in different units.
  • Converting network bandwidth figures (Mbps) to file-transfer sizes (MB) to estimate download times.
  • Developers checking upload limits, buffer sizes, or memory allocations when building APIs or embedded systems.
  • Students and IT professionals studying computer architecture, operating systems, or networking fundamentals.

How to use

  • Type a numeric value into the input field (for example: 2048).
  • Select the source unit from the dropdown (for example: MB).
  • All equivalent values in every other unit appear instantly below.
  • Click any copy icon to send a specific result to your clipboard.

Frequently asked questions

How many MB are in 1 GB? In binary (the standard used by operating systems), 1 GB = 1,024 MB. Hard drive manufacturers use decimal, where 1 GB = 1,000 MB, which is why advertised capacities look smaller once formatted.

Why does a 1 TB drive show only about 931 GB on my computer? Manufacturers define 1 TB as 1,000,000,000,000 bytes (decimal), while Windows divides by 1,024 three times to get gigabytes — this converter lets you verify that difference instantly.

What is the difference between a megabit and a megabyte? 1 megabyte (MB) = 8 megabits (Mb). Internet speeds are usually quoted in megabits per second (Mbps), while file sizes are in megabytes (MB), so divide your Mbps speed by 8 to get the MB/s download rate.

Does the tool support kibibytes (KiB) and mebibytes (MiB)? The converter uses standard everyday labels (KB, MB, GB) while applying IEC binary math underneath, which matches how most users and operating systems refer to these units in practice.
