Sid 2020-01-16 10:27:53Papacarlo, you're wrong. One gigabit is equal to 1,000,000,000 bits, you're talking about gibibit which is different. ...

Thank you for giving free service ...

This is wrong calculator. Use computer science and not a grocery store measurements. 1K1024 so 1 gigabit 1073741824 bits but not anyhow 1000000000 bits. ...
