25 Gbit/s at home, part 1

To convert MB/s to gb/s (MegaBytes per second to Gigabits per second) simply multiply by 8 (8 bits per byte). So 280MB/s is 2.24gbps (moving the decimal place).

> but I always multiply transfers times 10 to estimate bandwidth, since there is some overhead in the TCP/IP protocol

20%ish seems high though, especially for file transfers which are probably almost all full packets near 1500 MTU cross WAN.

There is another variable as well. Most network equipment I've worked with reported throughput with incorrectly labeled kibi/mibi/gibi, and the ISP uses kilo/mega/giga.

The former system is multiples of 1024, the latter the mathematical and legal definition of x1000

The X10 rule of thumb is probably pretty spot on at the end

What godforsaken gear reports in binary prefixes? That's just... horrendous.
