Convert Digital Storage Like a Pro

Ever bought a 1 Terabyte (TB) hard drive only to find your computer says it only has 931 Gigabytes (GB) of space? This confusion happens because hard drive manufacturers use decimal math (1 KB = 1000 Bytes), while computers use binary math (1 KB = 1024 Bytes).

Our Data Storage Converter uses the binary system (base 1024) which matches exactly how your Windows PC or smartphone operating system reads file sizes. Quickly convert between Bytes, KB, MB, GB, and TB to know exactly how much space your files take up.

Frequently Asked Questions

In the binary system used by computers, there are exactly 1,024 Megabytes (MB) in one Gigabyte (GB).

Manufacturers define 1 GB as 1,000,000,000 bytes. Windows defines 1 GB as 1,073,741,824 bytes (1024^3). Thus, a 500,000,000,000 byte drive shows up as about 465 GB in Windows.

A bit is the smallest unit of digital data, representing a 1 or a 0. A byte consists of 8 bits. Storage space is measured in Bytes (uppercase B), while internet speed is often measured in bits (lowercase b), like Mbps.
