Conversion tips

  • 1 byte = 8 bits
  • 1 KB = 1,000 bytes; 1 KiB = 1,024 bytes
  • Windows often shows GiB while labels say GB

Data Storage & Bandwidth Converter

Storage is confusing because some labels use powers of ten and others powers of two. That’s why a “terabyte” drive and your OS can disagree. This tool separates decimal SI steps from binary IEC steps so you can see both stories clearly.

Why these units exist

IEC introduced KiB/MiB to disambiguate 1024-multiples from SI marketing GB; operating systems still report GiB-ish numbers while SSD boxes quote decimal TB.

Decimal vs binary ladders

Bytes_target = Bytes_source × (multiplier for source) / (multiplier for target), with independent SI vs IEC ladders.

Pick whether each step is 1000× (kilo, mega…) or 1024× (kibi, mebi…). Mixing ladders mid-stream is how “missing” drive space appears.

Four ideas worth memorizing

  • 1SI GB = 10⁹ bytes; GiB = 2³⁰ bytes—closest marketing “GB” to OS GiB.
  • 21 byte = 8 bits always—don’t mash bit-rate and byte storage without ÷8.
  • 3Bandwidth is often bits/sec; storage is bytes—watch prefixes twice.
  • 4Excel’s 1024 flag changes display; it doesn’t change marketing math.

How to Convert Data Units

Short version: To convert Megabytes (MB) to Gigabytes (GB), divide the value by 1,000 (standard decimal) or 1,024 (binary/Gibibytes).

  1. Select your starting unit (e.g., Megabytes).
  2. Enter the value you want to convert.
  3. Choose your target unit (e.g., Gigabytes).
  4. The result appears instantly using the base-10 (Decimal) or base-2 (Binary) standard.

Frequently asked questions

What is the difference between MB and MiB?

MB (Megabyte) uses decimal base-10 (1,000 KB), while MiB (Mebibyte) uses binary base-2 (1,024 KiB). Modern operating systems often mix these terms.

How many bits are in a byte?

There are exactly 8 bits in 1 byte.

Why do cloud bills use decimal GB?

Providers meter stored objects with decimal TB for accounting consistency; kernels may still allocate binary pages underneath.
