How this data size converter works
This Data Size Converter uses byte as the internal base unit. Your input is first converted
into bytes using high-precision factors, then divided by the factor for the target unit.
The right-hand list shows how much 1 From unit equals in every other unit so you
can scan all equivalents at once.
Common conversion facts
- 1 byte [B] = 8 bit [b]
- 1 kilobyte [kB] = 1024 bytes
- 1 megabyte [MB] = 1,048,576 bytes
- 1 gigabyte [GB] = 1,073,741,824 bytes
Why use an online data size converter?
A dedicated data size converter is helpful whenever you move between
networking, storage and operating-system units. Hard drive manufacturers often use decimal
prefixes such as “GB” based on powers of ten, while operating systems display binary sizes
based on powers of two. This can make the same device appear to have different capacities.
Instead of manually calculating factors for every conversion, this page lets you select a
unit once and instantly see all equivalents. If you need to multiply or divide a value
before conversion, you can open the built-in scientific calculator, evaluate an expression
such as (150 × 1024), and send the result directly into the “From” box.
Popular conversions you can do here
- Bit to byte and byte to bit when working with network speeds and file sizes.
- KB to MB and MB to GB for application requirements, backups and cloud storage.
- GB to TB for disk capacity planning and server provisioning.
- Binary vs decimal prefixes using kilobyte [kB] and megabyte [MB] versus their 103 counterparts.
- Floppy, Zip, Jaz, CD and DVD sizes for digital archiving and restoring legacy media.
How to read the right-hand list of units
The left list controls which unit you are converting from. When you click any entry,
the list on the right is refreshed to show how much 1 of that unit equals in every
other unit in the database. For example, if you select “megabyte [MB]” as the From unit, the right list
will show:
- 1 MB = 8,388,608 bit
- 1 MB = 1,048,576 byte
- 1 MB ≈ 0.0009536743 GB
- …and more for each supported unit.
This reference-style layout matches traditional engineering converters and makes it easy to compare
units without running multiple separate calculations.
Accuracy, rounding and large numbers
All conversion factors are stored with high precision. Very large and very small values are formatted
so they remain readable, and extremely large numbers are shown using scientific notation when needed.
This is particularly useful when working with petabytes and exabytes or very small units such as bits.
Who benefits from this tool?
- Developers and system administrators sizing databases, server storage and log archives.
- Students learning about binary and decimal units in computer science courses.
- IT professionals preparing reports and capacity plans for clients or management.
- Everyday users comparing download sizes, backup archives and media capacities.
Final note
This data size converter is intended for general information and planning. For compliance,
billing or legal reporting you should always confirm numbers with official documentation and
vendor specifications. For quick everyday conversions, this page gives you a clean, accurate
and distraction-free way to move between any common data storage unit.
