2,750um to Mm
CF=10^12 2,750um=2,750*10^-12

What does CF stand for.
small to big you divide, so why don't
I divide by 5 lots of 1000. Can you please give me some examples of conversions like this one. Thanks

• math -

CF probably stands for conversion factor. It is not a commonly used abbreviation.

You are converting micrometers (10^-6 m) to Megameters (10^6 m)

You would do the conversion by multiplying
2.750 um by 10^-12 Mm/um
10^-12 Mm/um is the "CF"
