Why is 100 Mbps only 12.5 MB/s?

Bits vs bytes: 1 byte = 8 bits. So 100 megabits per second divided by 8 = 12.5 megabytes per second. Network speeds are in bits; file sizes are in bytes.

What is the difference between MB/s and MiB/s?

MB/s uses decimal prefixes (1 MB = 1,000,000 bytes), MiB/s uses binary (1 MiB = 1,048,576 bytes). This tool shows both columns.

How fast is 5G in Mbps?

Typical 5G downloads are 300-500 Mbps, peak up to 1 Gbps. That is 37.5-62.5 MB/s, enough to download a 5 GB movie in about 80 seconds.

ISP speeds are advertised in megabits per second, but file downloads show megabytes per second — an 8x gap. Also handles binary (KiB, MiB) vs decimal (kB, MB) prefixes.
