Digital Unit Converter – Bits, Bytes, KB, MB, GB, TB, PB Conversion Tool
This tool allows quick and accurate conversions between bits, bytes, and larger digital units. It supports kilobytes, megabytes, gigabytes, terabytes, and petabytes.
Simply enter a value, select the units, and get instant results. The converter follows the binary system, where 1 KB = 1024 bytes, ensuring precise calculations used in operating systems and programming. It is useful for file size conversions, internet speed calculations, storage planning, and general data measurement. The tool works seamlessly on desktop, tablet, and mobile devices.
All digital units relative to 1 byte (B). Binary (1 KB = 1024 B).

Understanding Digital Storage Units
Digital information is measured in bits and bytes. A bit (b) is the smallest unit (0 or 1). A byte (B) is 8 bits and is the basic unit for file sizes. Larger units use prefixes: kilo (K), mega (M), giga (G), tera (T), peta (P). In computing, these are usually binary (powers of 1024), though storage devices are often marketed using decimal (powers of 1000).
Binary vs. Decimal Confusion
1 kilobyte (KB) can mean either 1000 bytes (decimal) or 1024 bytes (binary). This tool uses the binary interpretation (1 KB = 1024 B), which is standard in operating systems and programming. For clarity: MB = 1024² bytes, GB = 1024³, TB = 1024⁴.
Typical Scenarios
- Bits (b) – network speeds (Mbps, Gbps), processor architecture (32-bit, 64-bit).
- Bytes (B) – file sizes (a text file is a few KB, a photo is MB).
- Megabytes (MB) / Gigabytes (GB) – RAM, SSD/HDD capacity, video file sizes.
- Terabytes (TB) / Petabytes (PB) – data center storage, large databases.
