What is a data storage converter?
A data storage converter changes a quantity from one digital storage unit to another. It can turn bytes into kilobytes, megabytes into gigabytes, or terabytes into smaller units. This is handy when comparing file sizes, estimating download space, choosing a storage plan or checking whether a drive has enough capacity.
Enter an amount, choose the unit it starts in and select the unit you want to see. The converted value and a list of equivalent units update immediately. Every calculation happens in your browser, so no file or value is uploaded to a server.
Decimal and binary units
- Decimal storage uses groups of 1,000: 1 KB is 1,000 bytes, 1 MB is 1,000 KB and 1 GB is 1,000 MB.
- Binary storage uses groups of 1,024: 1 KiB is 1,024 bytes, 1 MiB is 1,024 KiB and 1 GiB is 1,024 MiB.
- A byte contains eight bits, so the converter can also move between bits and byte-based units.
Drive manufacturers commonly use decimal labels such as GB and TB. Operating systems and memory documentation may use binary values, sometimes labeled KiB, MiB, GiB and TiB. That difference explains why a new drive can show a smaller capacity after you connect it to a computer: the number of bytes has not changed, but the unit convention has.
How to use the converter
Choose Decimal when a specification uses KB, MB, GB or TB in powers of 1,000. Choose Binary when it explicitly uses KiB, MiB, GiB or TiB, or when you need powers of 1,024. Then enter the quantity, select the original unit under From and choose a target unit under To. The equivalent-values grid is useful for seeing several common representations at once.
For example, 1 GB is 1,000 MB in the decimal system. In binary terms, 1 GiB is 1,024 MiB. Do not treat GB and GiB as interchangeable when accuracy matters, especially for backups, hosting, RAM or technical purchase decisions.
Why convert storage units?
Clear unit conversions make it easier to estimate transfer time, check attachment limits and compare cloud-storage offers. They also prevent small-looking differences from becoming confusing at large sizes. For billing, hardware requirements or a provider's stated capacity, use the unit convention written in that service's terms. This converter gives you a quick local calculation, while the original specification remains the final reference.
