"bits per second" is what it always has been for computer communication.
When I got started, I got a 300 bits/second modem, which later got upgraded to 1200/75 bits/s and then 2400 bits/second.
Later on, we had 57,6 kbit/second modems, 64 kbit/s ISDN lines, 2 Mbit/s ADSL, etc.
All the speedtest websites I've seen also use Mbit/s.
But sure, if I'm downloading the latest Ubuntu distro, I want to know the current speed in Megabytes/s.
