Data Converter
Convert between all 10 data units — Bit, Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Kibibyte, Mebibyte, Gibibyte, Tebibyte — with instant results, formulas and worked examples.
A single converter for every data unit on ConvertWorks. Pick any two units, type a value, and get an instant, accurate result — no page reloads and nothing leaves your browser. Dedicated pages for the most popular pairs are linked below.
Quick reference — Bits to Bytes
Every unit above is defined relative to the bytes: pick any pair and the converter divides the two base factors, so results stay consistent across the whole category.
How to use this calculator
- Choose the unit you have in the From dropdown.
- Choose the unit you want in the To dropdown.
- Type your value — the result updates instantly.
- Use Swap to reverse the conversion, or open a dedicated pair page below for one specific conversion.
The formula
Result = Value × (from-unit factor ÷ to-unit factor), with all factors relative to the bytes.
Worked example
5,000 MB = 5 GB — in full, 5,000 Megabytes converts to 5 Gigabytes. File sizes, downloads and storage specs are the everyday jobs for this conversion.
Frequently Asked Questions
What units does this data converter include?
It covers Bit, Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Kibibyte, Mebibyte, Gibibyte, Tebibyte — 10 units in total. Every conversion runs through the bytes as the common reference, so any pair you pick stays consistent with every other pair.
How does this data converter work?
Each unit is defined by an exact factor relative to the bytes. To convert, the tool multiplies your value by the from-unit's factor and divides by the to-unit's factor, then rounds the display to six significant figures.
How accurate are the results?
The factors come from the official definitions of the units (for example, 1 inch is exactly 0.0254 meters and 1 pound is exactly 0.45359237 kilograms), so conversions are as accurate as the definitions themselves. Display rounding to six significant figures can hide trailing digits on extreme values.
Can I convert Megabytes to Gigabytes with this tool?
Yes — select Megabytes and Gigabytes in the dropdowns. For example, 5,000 Megabytes equals 5 Gigabytes, and the dedicated pair page linked below focuses on just that conversion.
Why are kilobytes and kibibytes both listed?
A kilobyte (KB) is 1,000 bytes in the SI system used by storage manufacturers, while a kibibyte (KiB) is 1,024 bytes in the IEC binary system most operating systems report in. Both are listed so you can match the number to the context you are reading.
