You can measure bacteria in nano grams as only 1,000,000,000 nano grams are in 1 gram ,so that you might not even be able to see the object what you weighing in nano gram.
Nano is 10-9. e.g. nanometer= .000000001m
less than nano gram
The symbol for Nanometrics Incorporated in NASDAQ is: NANO.

The symbol for nanometer is nm.
Nano is a prefix meaning 1/1000 000 000 or a thousand millionths. There are 1 000 000 000 ng = 1 g
0.5 micro gram = 0.5 x 1000 = 500 nano grams. Hence 779.4 nano grams is greater than 0.5 micro grams by 279.4 nano grams

To fix a frozen ipod nano hold the "MENU" and CENTRE button. Hold for 5 seconds then release. Your ipod nano will go to the apple symbol then turn back to normal.
nano is 10 to the power of -9, micro is 10 to the power of -6 and so number of nano grams in i micro gram is 10 to the power of -6 divided by 10 to the power of -9, giving an answer of 1000
