A little guidance.
Calculate the ideal transfer time from a file size and a constant data rate. Decimal units (MB, GB) differ from binary units (MiB, GiB), and bits differ from bytes. Network overhead, contention, and protocol latency are excluded.

Good to know.
Why is my actual download slower?
This is a theoretical best-case estimate. Advertised rates, wireless conditions, server limits, and transfer overhead affect real download time.
Is my input sent to a server?
No. This tool runs in your browser. KILIZU does not upload or store the values or files you enter here.
