Does Micro and a billionth mean the same thing?

So, you have Micrometer for metric and MicroYard/Foot/Inch for imperial?

Perhaps you are joking, but no -
even with Imperial measure the tool is still called a "micrometer".
However, there is a unit called the "micro-inch" which is one millionth of an inch.
It is not used very often outside of laboratory conditions, and maybe not even then.
It was more common back in the 1960's.

For me, Micrometer means a measuring device to measure with micro precision and, sure I was joking on the earlier post. Just because it mentions meter doesn't have to be related to metric.
