Bits vs bytes?

Speeds are sold in megabits (Mb/s); files are measured in megabytes (MB) — 8 bits per byte.

Why slower than promised?

Protocol overhead, congestion and Wi-Fi losses; the calculator already subtracts 10%.

How to speed up transfers?

Use a wired connection, parallel streams or a closer server/CDN.
