Data Storage Converter

Convert between data storage units including bytes, kilobytes, megabytes, gigabytes, terabytes, and more instantly. Free data storage converter for computer science and IT.

Smart Tips

• Storage manufacturers often use decimal (1 GB = 1,000 MB) while operating systems use binary (1 GiB = 1,024 MiB)

• This difference explains why a "500 GB" drive shows less capacity in your computer

• For network speeds, remember that 1 byte = 8 bits (Mbps vs MBps)

• Cloud storage and SSDs are measured in decimal, while RAM uses binary

The Formula

Converted Size = Original Size × Conversion Factor

Original Size = Size in source unit
Input data size value

Conversion Factor = Unit conversion ratio
1 KB = 1,024 bytes on this page

Converted Size = Result in target unit
Binary units (KB, MB, GB) use 1024-based conversion

Data Storage Conversion Reference

Unit	Conversion
Bit (b)	Smallest unit, 1 bit = 1/8 byte
Byte (B)	Base unit, 1 B = 8 bits
Kilobyte (KB)	1 KB = 1,024 bytes on this converter
Megabyte (MB)	1 MB = 1,024 KB on this converter
Gigabyte (GB)	1 GB = 1,024 MB on this converter
Terabyte (TB)	1 TB = 1,024 GB on this converter

Key Insights

Binary vs Decimal

This page uses 1,024. Some device labels use 1,000, which this converter does not.

Common Units

Bytes, KB, MB, GB, TB are the most commonly used units, with each level representing 1024 times the previous unit.

File Size Context

Understanding storage units helps estimate file sizes, device capacity, and data transfer requirements.

Practical Applications

Use conversions for comparing storage devices, calculating download times, and managing digital storage space.

Frequently Asked Questions

Select your input unit, enter the storage value, choose your target unit, and our converter will instantly provide the converted value. Every step uses powers of 1024. 1 KB = 1,024 bytes. There is no 1,000-byte option.

This converter uses powers of 1024 only. The labels KB, MB, and GB here mean 1,024, not 1,000. It does not convert decimal (SI) prefixes.

Our converter uses precise conversion factors and provides accurate results to multiple decimal places. Every step uses powers of 1,024 (IEC binary prefixes, https://www.iec.ch/prefixes-binary-multiples).

We support bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes, zettabytes, and yottabytes. The converter uses powers of 1024 only, from the bit (1/8 byte) through the yottabyte.

Different systems evolved for different purposes: binary units for computer memory (1024-based) and decimal units for storage devices (1000-based). Both are valid and widely used in different contexts.

Each step multiplies or divides by 1,024. A bit is 1/8 byte. The labels use KB, MB, and GB for those binary amounts. This page does not offer the 1,000-byte SI prefixes. The 1,024 convention is the binary-prefix size described by the IEC.

Note: This converter always uses powers of 1,024. Storage packaging often uses 1,000 instead, so compare that convention separately.
