The Data Storage Converter (General) is a comprehensive tool for converting between all common units of digital data storage and measurement. Whether you need to convert gigabytes to megabytes, bits to bytes, or any other combination, this converter handles it instantly using binary (base-2) prefixes where 1 KB = 1024 bytes.
Digital data storage is measured in a hierarchy of binary units, each 1024 times larger than the previous. This binary system originates from computer architecture, where memory is addressed in powers of 2. The fundamental unit is the bit (binary digit, 0 or 1), the smallest unit of information in computing. Eight bits make one byte, which can represent a single character, a number from 0-255, or other data.
Our converter uses the traditional binary interpretation: 1 KB = 1024 B, 1 MB = 1024 KB = 1,048,576 B, 1 GB = 1024 MB = 1,073,741,824 B, 1 TB = 1024 GB, 1 PB = 1024 TB. This matches how operating systems (Windows, macOS, Linux) report file sizes and how RAM is measured. Note that hard drive manufacturers use decimal (SI) prefixes where 1 KB = 1000 bytes, which is why a "1 TB" drive shows as approximately 931 GB in your operating system.
The converter also supports less common units: nibbles (4 bits, one hexadecimal digit), words (16 bits / 2 bytes, a common processor data unit), and quadruple words (64 bits / 8 bytes, the native data width of modern 64-bit processors).
The converter works by first converting the input to bytes, then converting from bytes to the target unit. Binary conversion factors: 1 byte = 8 bits, 1 nibble = 4 bits = 0.5 bytes, 1 word = 2 bytes, 1 qword = 8 bytes, 1 KB = 1024 bytes, 1 MB = 1024² bytes, 1 GB = 1024³ bytes, 1 TB = 1024⁴ bytes, 1 PB = 1024⁵ bytes.
Common storage references: a text email is about 5-50 KB, a smartphone photo is 2-8 MB, a song (MP3) is 3-10 MB, an HD movie is 3-8 GB, a modern video game is 50-150 GB, and a typical hard drive holds 1-8 TB. Cloud data centers store petabytes of data.

In traditional computing (and this converter), 1 KB = 1024 bytes (binary). Hard drive manufacturers use 1 KB = 1000 bytes (decimal/SI). The IEC introduced KiB (kibibyte) = 1024 bytes to resolve this ambiguity.
Manufacturers measure in decimal (1 TB = 10¹² bytes), while your OS displays in binary (1 TB = 1024⁴ bytes). A '1 TB' drive is 1,000,000,000,000 bytes = 931.32 GiB as your OS sees it.
A bit is the smallest unit of data (0 or 1). A byte is 8 bits. Internet speeds are measured in bits per second (Mbps), while file sizes are in bytes (MB). 100 Mbps = 12.5 MB/s.
A nibble is 4 bits (half a byte). It represents one hexadecimal digit (0-F). Nibbles are used in low-level programming, hardware design, and encoding schemes.
A word is a natural data unit for a processor. In this converter, 1 word = 16 bits = 2 bytes (common in embedded systems). Modern 64-bit processors use 64-bit words (8 bytes), called quadruple words (qwords).
1 PB = 1024 TB = 1,125,899,906,842,624 bytes (binary). That is approximately 1.126 × 10¹⁵ bytes.
Common units go up to exabytes (EB, 1024 PB), zettabytes (ZB, 1024 EB), and yottabytes (YB, 1024 ZB). Global data creation reached approximately 120 zettabytes in 2023.
These are IEC binary prefixes: KiB (kibibyte) = 1024 bytes, MiB (mebibyte) = 1024², GiB (gibibyte) = 1024³. They were introduced to distinguish binary (×1024) from decimal (×1000) prefixes unambiguously.
Divide bits by 8 to get bytes. A 100 Mbps internet connection transfers 12.5 MB/s. Network speeds use bits; download managers show bytes.
Modern smartphone photos use 2-8 MB depending on resolution and format. A 128 GB phone can store roughly 16,000-64,000 photos, plus apps, videos, and OS.
