Where you'll actually use this
Data storage units measure information — bits, bytes, and their multiples. The catch: decimal (kB = 1,000 B) and binary (KiB = 1,024 B) systems both exist and are often confused.
- Cloud storage & quotas
Providers usually quote storage in GB (decimal). Operating systems often report in GiB (binary), which is why a '1 TB' drive shows up as ~931 GiB.
- Network bandwidth
Internet speeds are quoted in Mbps (megabits per second), not MB/s. Divide by 8 to get download MB/s.
- Media files
Video bitrates, photo file sizes, and database row counts all need fluent byte-multiple conversion.
Common mistakes to avoid
- Bits vs bytes
Lowercase b = bit, uppercase B = byte. 1 byte = 8 bits. 100 Mbps ≠ 100 MB/s.
- MB vs MiB
1 MB = 1,000,000 B. 1 MiB = 1,048,576 B. The difference grows the larger you go — about 10% at the TB/TiB level.
Did you know?
Drive makers use decimal GB (1,000³). Operating systems show binary GiB (1,024³). A 1 TB drive really is 1 TB — just 931 GiB.
