Anything to one decimal place has a precision of one decimal place. For instance, 1234 to one decimal place is 1000, and 5678 to one decimal place is 6000. If you are talking fractional examples, then 0.1234 to one decimal place is 0.1 and 0.5678 to one decimal place is 0.6. Similarly, 0.001234 is 0.001, and 0.005678 is 0.006.
'Nano-' denotes a fraction of one billionth (10-9)A nanogram (ng) is, therefore, 10-9gor one billionth of a gram. This can be written as a unit in the 9th decimal place: 0.000000001g.Similarly:10-6g = 1 microgram (µg)...10-12g = 1 picogram (pg)10-15g = 1 femtogram (fg)and so on.
