What is the Data Storage Converter?

Convert any data storage unit to all others at once — bit, B, KB, MB, GB, TB, PB. Storage sizes are measured in bytes, kilobytes, megabytes and beyond, and decimal versus binary units explain why drives look smaller than advertised.

How to use the Data Storage Converter

  1. Enter your value, your from unit.
  2. Results update automatically as you type; you can also press Calculate.
  3. Read the output: bit (bit), byte (b), kilobyte (kb), megabyte (mb).
  4. Check the chart to see how the conversion scales.

Formula and method

value in target = value × (factor of source ÷ factor of target)

Worked example

With value = 1, from unit = Bit (bit), the Data Storage Converter returns bit (bit): 1 bit; byte (b): 0.125 B; kilobyte (kb): 0.000125 KB.

When an all-in-one data storage converter helps

You bought a 1 TB external drive and your computer shows about 931 GB. Converting between decimal terabytes and binary gibibytes shows nothing is missing.

A web developer needs to know how many 250 KB images fit within a 5 MB email limit. Converting units gives a quick answer.

Watch out for these mix-ups

  • Mixing decimal units (1 KB = 1,000 bytes) with binary units (1 KiB = 1,024 bytes).
  • Confusing bits with bytes in internet speeds.
  • Assuming formatted capacity equals advertised capacity.
  • Ignoring file-system overhead.

Tips for better results

  • Divide megabits per second by 8 to get megabytes per second.
  • Use binary units when matching operating-system reports.
  • Leave spare space on drives for performance.

💡 Practical tip: Internet speeds use bits, so a 100 Mbps connection downloads about 12.5 megabytes per second at best.

Frequently asked questions

What does the Data Storage Converter do?
