Digital Converter
Fast, accurate digital conversions, right in your browser.
The Digital Storage Converter converts data size between common units — bytes, kilobytes, megabytes, gigabytes — instantly and accurately. Enter a value in one unit and see it converted to all supported units at once.
Whether you're working on an engineering calculation, a recipe, a science assignment or converting specs from an international source, this tool eliminates manual conversion-factor lookups and rounding errors.
How to Convert data size
- Enter your value and select the starting unit
- Choose the unit you want to convert to
- The converted result appears instantly
Best Practices
- Double-check which unit variant is expected (e.g. US vs. metric) for your specific use case
- For engineering or scientific work, verify precision requirements against the tool's decimal output

Frequently Asked Questions
What units does this digital storage converter support?
Common units include bits, bytes, kilobytes, megabytes, gigabytes, and terabytes.
How many megabytes are in a gigabyte?
1,024 megabytes in a gigabyte using the binary (1024-based) standard, or 1,000 megabytes using the decimal (1000-based) standard — storage manufacturers and operating systems sometimes use different conventions.
Why does my hard drive show less storage than advertised?
Manufacturers typically use the decimal definition (1 GB = 1,000,000,000 bytes) while operating systems often display storage using the binary definition (1 GB = 1,073,741,824 bytes), making the same drive appear smaller in your OS than on the box.
What's the difference between a bit and a byte?
A byte equals 8 bits. Bits are typically used for measuring data transfer speed (like Mbps), while bytes are used for file and storage sizes (like MB).
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — conversions run in your browser and the values you enter are not stored or sent to a server.
How many gigabytes are in a terabyte?
1,024 gigabytes in a terabyte (binary) or 1,000 gigabytes (decimal).
Is this useful for estimating download or file transfer size?
Yes — converting between megabits (Mb, used for internet speed) and megabytes (MB, used for file size) is a common source of confusion this tool can help clarify.
What's the difference between Mb and MB?
Mb (lowercase b) means megabits, commonly used for internet speed; MB (uppercase B) means megabytes, used for file sizes. 1 MB = 8 Mb.
Does this support petabytes or larger units?
Larger storage units like petabytes are typically included for enterprise-scale storage conversions, alongside the more common everyday units.
