What is Data Storage Unit Conversion?
Data storage unit conversion is the process of expressing the same amount of digital information in a different unit — for example, converting megabytes to gigabytes or GB to TB. All storage units are derived from the bit (the smallest unit of digital data) and the byte (8 bits). The data storage converter uses bits as the base unit: every input is first converted to bits, then scaled to the target unit using the correct factor for the chosen standard (decimal or binary).
How Our Data Storage Converter Works
- 1Choose your standard: Select Decimal (SI) for hard drive and network contexts, or Binary (IEC) for OS-reported file and RAM sizes.
- 2Select your units and enter a value: Pick the source unit (From) and target unit (To), then type any positive number. Use the swap button to instantly reverse the direction.
- 3Get your result instantly: Click Convert to see the converted value. Expand the all-units table to view the equivalent in every supported storage unit simultaneously.
What Gets Converted
- Bits & Bytes: The fundamental units — 1 byte = 8 bits. Used for measuring individual file sizes and memory addresses.
- Decimal Units (KB, MB, GB, TB, PB, EB): Each step is a factor of 1,000. Used by hard drive manufacturers, SSDs, USB drives, and network speed ratings.
- Binary Units (KiB, MiB, GiB, TiB, PiB): Each step is a factor of 1,024. Used by operating systems (Windows, Linux, macOS) when reporting RAM, file sizes, and partition sizes.
- Nibble: A group of 4 bits, equal to half a byte. Used in low-level programming, hexadecimal notation, and networking protocols.
Decimal (SI) Standard
Defined by the International System of Units. 1 KB = 1,000 B, 1 MB = 1,000,000 B, 1 GB = 1,000,000,000 B. Used by storage manufacturers and ISPs because it makes drives appear larger.
Binary (IEC) Standard
Defined by the International Electrotechnical Commission in 1998. 1 KiB = 1,024 B, 1 MiB = 1,048,576 B, 1 GiB = 1,073,741,824 B. Used by operating systems for accurate memory and file reporting.
Why the Discrepancy?
A 1 TB drive (decimal) = 1,000,000,000,000 bytes. Your OS reads this as ~931 GiB (binary). The data storage converter lets you switch between both standards to understand the exact difference.

A data storage converter is a tool that converts a digital storage measurement from one unit to another — for example, from megabytes to gigabytes, or from GB to TB. Our data storage converter supports 14 units including bits, bytes, KB, MB, GB, TB, PB, EB, and all IEC binary units (KiB, MiB, GiB, TiB, PiB), and runs entirely in your browser with no signup required.
In the decimal (SI) standard used by storage manufacturers, 1 GB = 1,000 MB. In the binary (IEC) standard used by operating systems, 1 GiB = 1,024 MiB. Use the data storage converter above and select your preferred standard to get the exact result.
1 TB (terabyte, decimal) = 1,000 GB. 1 TiB (tebibyte, binary) = 1,024 GiB. Hard drive manufacturers use the decimal standard, which is why a "1 TB" drive appears as approximately 931 GiB in your operating system.
MB (megabyte) uses the decimal standard: 1 MB = 1,000,000 bytes. MiB (mebibyte) uses the binary IEC standard: 1 MiB = 1,048,576 bytes. The difference is about 4.86%. Operating systems like Windows and Linux use MiB internally but often display the label "MB", which causes confusion. Our data storage converter lets you switch between both standards.
Hard drive manufacturers define 1 TB as 1,000,000,000,000 bytes (decimal). Windows reports storage in binary GiB: 1,000,000,000,000 ÷ 1,073,741,824 ≈ 931 GiB. No storage is missing — it's simply a difference in measurement standards. Use the data storage converter to verify: convert 1 TB (decimal) to GiB (binary) and you'll get exactly 931.32 GiB.
To convert MB to GB using the decimal standard, divide the number of megabytes by 1,000. For example, 5,000 MB ÷ 1,000 = 5 GB. Using the binary standard, divide MiB by 1,024 to get GiB. Enter your value in the data storage converter above, select MB as the source and GB as the target, and click Convert.
A bit is the smallest unit of digital data — it holds a single binary value of 0 or 1. A byte is a group of 8 bits and is the standard unit for measuring file sizes and storage capacity. Network speeds are typically measured in bits per second (Mbps), while file sizes are measured in bytes (MB, GB). To convert between them, multiply or divide by 8.
