What is the difference between GB and GiB?

Byte (B): 8 bits, fundamental unit
Kilobyte (KB): 1,000 Bytes
Megabyte (MB): 1,000 KB
Gigabyte (GB): 1,000 MB
Terabyte (TB): 1,000 GB
Petabyte (PB): 1,000 TB

GB = 1000³ bytes (decimal), GiB = 1024³ bytes (binary). Operating systems often use GiB but label it as GB.

How much data is 1 TB?

1 TB = 1,000 GB. A typical laptop hard drive ranges from 256 GB to 1 TB.

Operating systems use binary units (GiB), but manufacturers use decimal (GB). This causes apparent size differences.

Convert between digital storage units: Byte, KB, MB, GB, TB, and PB.

Convert between digital storage units used in computing. 1 Byte = 8 bits, the fundamental unit of digital data.

A typical movie file is 2 GB. How many MB is that?

GB = 1000³ bytes (decimal), GiB = 1024³ bytes (binary). Operating systems often use GiB but label it as GB.
