Data Storage Converter
Convert bits, bytes, KB, MB, GB, TB, and PB in bases 10 (SI) and 2 (IEC).
Base 10 (SI - Decimal) (SI)
Base 2 (IEC - Binary) (IEC)
How it works
Convert file sizes and disk capacities between two major scale definitions: decimal (Base 10 / SI) used by storage manufacturers, and binary (Base 2 / IEC) used by operating systems.
Frequently asked questions
What is the difference between GB (Gigabyte) and GiB (Gibibyte)?
A Gigabyte (GB) is based on the decimal system (10^9 or 1,000,000,000 bytes), whereas a Gibibyte (GiB) is based on the binary system (2^30 or 1,073,741,824 bytes), resulting in a difference of about 7.3%.
Why does my hard drive show less capacity in my OS?
Hardware manufacturers sell drives using the decimal scale (Base 10), while OS platforms like Windows measure space in binary scale (Base 2). A drive sold as 500 GB appears as approximately 465 GiB.
How many bits are in a Byte?
Exactly 8 bits make up 1 Byte of digital information.
