Nano Meter

[oxo1947]

I just ordered a small electrical part from the internet (lazada) & and found the sizing in the diagram to be 1247 NM --thinking this just print error & meant MM= Millimeter  converted it and found it way to large. 

 

Goggle informed me it is 1 NM is 1 millionth of a meter --in school (way back in the 50s) we used a micrometer , or a Vernier calipers to measure down to one thousandth of an inch.

 

Up until yesterday I had never heard of a NM...............Nano Meter  

 

 

Anyway--just stick this post away in the pub, I am sure it will have 1 NM interest to most readers..................

Actually it is nm, NM is a Newton Mega which doesn't make sense.

 

Does this count as a grammar-police post and I will have to delete it?

Maybe meant Microns (µm) but didn't have a Greek Mu on the keyboard - that would be 0,1247cm.

You would need a good microscope to see if what you ordered actually turned up 😛

 

Maybe 1247 nm is 1.247 microns ?? tiny

In this case (Shirley)  its referring to the wavelength of the laser beam ?

No it gives as size I just could not copy the picture----Lazada has some sort software  that does not let you ----I would post a link but I think thats allowed.....

Links to lazada are allowed. Even mods post them.
