Background

Data conversion is essential for storage, bandwidth, and computing. Key confusion: decimal (1 KB = 1,000 B) vs binary (1 KiB = 1,024 B). A '500 GB' drive shows ~465 GB in Windows.

Decimal vs Binary Prefixes

Storage makers: 1 GB = 10⁹ B. OS: 1 GB = 2³⁰ B. 7% discrepancy explains 'missing' storage.

Bits vs Bytes

1 byte = 8 bits. Internet speed in Mbps; file size in MB. 100 Mbps ≈ 12.5 MB/s.

Frequently Asked Questions

How many MB in a GB?

1 GB = 1,000 MB (decimal) or 1,024 MB (binary). OS uses binary; manufacturers use decimal.

Why does my drive show less space?

Makers use decimal GB (10⁹ B); OS uses binary (2³⁰ B). 500 GB drive shows ~465 GB.

How do you convert Mbps to MB/s?
