About this tool
Why does a "500 GB" drive show 465 GB in Windows? Because marketing uses decimal units (1 GB = 10⁹ bytes) while operating systems often count binary ones (1 GiB = 2³⁰ bytes). This converter handles both: bits, bytes, KB/MB/GB/TB and KiB/MiB/GiB side by side.
Enter one value and see it expressed in every unit at once — ideal for storage planning, bandwidth math and file-size sanity checks.
How to use
- Enter a size and its unit.
- Pick the target unit or swap.
- Read the result and the full table, decimal and binary.
Frequently asked questions
1 MB = 1,000,000 bytes (decimal); 1 MiB = 1,048,576 bytes (binary, 2²⁰). Drives are sold in MB/GB; many OSes display MiB/GiB — hence the "missing" space.
8. Internet speeds are quoted in bits (Mbps), file sizes in bytes (MB) — a 100 Mbps line downloads ~12.5 MB per second.
1,000 MB in the decimal system used for storage marketing; 1,024 MiB in a GiB.
