📚 Binary vs Decimal Units
Binary (1024-based)
1 KB = 1,024 Bytes
1 MB = 1,024 KB = 1,048,576 B
1 GB = 1,024 MB = 1,073,741,824 B
1 TB = 1,024 GB
Decimal / SI (1000-based)
1 Kb = 1,000 bits
1 Mb = 1,000 Kb = 1,000,000 b
1 Gb = 1,000 Mb = 1,000,000,000 b
Used for network speeds (ISP advertises in Mbps)
💡 Why does my 1 TB drive show 931 GB?
Drive manufacturers use decimal (1 TB = 1,000,000,000,000 bytes), but your OS reports in binary (1 TB = 1,099,511,627,776 bytes). The difference is ~7% for TB.
