Digital Data & Storage Units (Binary 1024)
In digital computing, storage capacity and RAM memory are counted in powers of 2. While storage manufacturers occasionally quote decimal prefixes (1 GB = 1,000 MB), computer operating systems (Windows, macOS, Linux) and file explorers calculate using binary prefixes (1 GiB / GB = 1,024 MB).
KB to MB to GB
1 KB = 1024 Bytes. 1 MB = 1024 KB. 1 GB = 1024 MB.
Terabytes & Petabytes
1 TB = 1024 GB. Modern SSDs, cloud drives, and backup systems.
Frequently Asked Questions
How many bytes are in 1 megabyte?
In binary notation, 1 MB = 1024 × 1024 = 1,048,576 bytes.
Why does a 1TB drive show 931 GB in Windows?
Drive makers sell 1,000,000,000,000 bytes as 1TB. When Windows divides by 1024³ to report binary gigabytes, it yields ~931.32 GB.
