Does Micro and a billionth mean the same thing?

[fjk]

For the standard SI numeric prefixes…
Micro is 1/1,000,000. (One million’th in the US)
nano is 1/1,000,000,000 (One billion’th in the US)

A microsecond is 1,000 nanoseconds long

when the prefixes are used colloquially, such as micropayment or nanoparticle, they tend just to mean “small” in some undefined way

I think billion has different meaning depending which side of the pond you are.

Both in the same number line right? The one is on the micro. .000,000

And the other on the macro 100,000.. Same number.

Anyway, back to the question. Why is our best measuring device called a Micrometer.

Them pesky Brits got in here and messed our measuring system I tell you LOL,,,
