if you're using speedtest.net it's gonna give it to you in bits
but if you're using steam or google chrome or something it's probably gonna tell you in bytes, which are just 8 times as big as a bit
like
1 or 0 are bits
0001011 or 01110001 or 10101010 are bytes
idk if that's how... anything works. but it's a good place to start maybe
