N'ihe banyere calculator a
A bandwidth calculator works out how long a file takes to transfer over a connection of a given speed, and the key to getting it right is the bits-versus-bytes distinction. File sizes are quoted in bytes — KB, MB, GB, TB — while connection speeds are quoted in bits per second — Kbps, Mbps, Gbps — and a byte is 8 bits. So the download time is the file size converted to bits (× 8), divided by the effective bit rate of the link. That single factor of 8 is why a connection’s headline number never matches the download figure you watch tick by.
As a worked example, a 1 GB file over a 100 Mbps connection is 1 GB × 8 = 8,000 megabits, and 8,000 / 100 = 80 seconds at the theoretical maximum — because 100 Mbps is only about 12.5 MB per second. Add a protocol-overhead allowance for the real world (TCP/IP headers, retransmissions, shared links) and the time stretches accordingly; a 10% overhead pushes that 80 s to about 89 s. The calculator also lists the speed expressed in bps, Kbps, Mbps, Gbps and MB/s for quick cross-checks.
You can switch between decimal units (1 KB = 1,000 bytes, the convention ISPs and drive makers use) and binary units (1 KiB = 1,024 bytes, how operating systems count), which shifts the numbers by a few percent — a "1 TB" decimal drive is about 931 binary GiB. This makes the tool handy for estimating backups and large downloads, sizing an internet plan, planning video streaming or uploads, and sanity-checking why a transfer is taking as long as it is.

Under the decimal convention 1 GB is 1,000,000,000 bytes, but operating systems often count in binary where 1 GiB is 1,073,741,824 bytes. Switch the byte-convention option to match how your file size was measured for an accurate transfer time.
