Step 1:
: Understand the conversion rate between grams and nanograms.

To express this in scientific notation, we write it as $$1 \times 10^9$$.
One gram is equal to 1,000,000,000 (1 billion) nanograms.

Step 2:
: To convert nanograms to grams, divide the number of nanograms by the conversion factor.

In this case, the conversion factor is $$1 \times 10^9$$.

Step 3:
: Since we want to convert 1 ng to grams, simply divide 1 by the conversion factor:

\frac{1}{1 \times 10^9} = 1 \times 10^{-9} \text{ g}

Final Answer

1 nanogram is equal to 1 \times 10^{- 9} \text{ g} in grams.
