7800nm + 95pm =

Yes Chris, I understand that but they must be used to measure something.

Here is an article

http://www.nanowerk.com/nanotechnology-news/newsid=36015.php

Picometres can be used to measure movement in atoms.  At least I think that is what the article is saying.

1 nm = 1000 pm so 95 pm = 0.095 nm 

You can do the addition.

.

What does pm stand for?  What are they used for?

Melody....I think "nm" and "pm" refer to nanometers and picometers......I could be wrong, however...!!!

Thanks Chris - do picometres measure atoms or molecules or what?

No...they are just linear parts of a meter.........
