About this tool

Drive shows 931 GB but the box said 1 TB? That's decimal GB vs binary GiB. This converter does both systems with exact factors (1 GiB = 1,073,741,824 bytes) and explains the difference right on the page — download times, hosting limits and storage shopping all become clear.

FAQ

Why does my 1 TB drive show 931 GB?

Drive makers use decimal TB (10¹² bytes); your OS shows binary TiB (2⁴⁰) and labels it TB. 1 TB = 0.909 TiB — hence 931 'GB'.

MB vs MiB?

MB = 10⁶ bytes (decimal), MiB = 2²⁰ = 1,048,576 bytes (binary) — both here.

Bits vs bytes?

8 bits = 1 byte — internet speeds are bits (Mb), file sizes are bytes (MB): divide speed by 8 for real MB/s.

Download time estimate?

Convert your file to megabits, divide by your Mbps speed — or just remember: 100 Mbps ≈ 12.5 MB/s.

Offline?

Yes.

Why 1024 vs 1000 matters?

Historical computing used 2¹⁰=1024; storage industry standardized 10³=1000 — the tool supports both honestly.
