Question

How many grams are $5.67ng$ ?

Answer 1

Hint : We all know the basic conversion that is $1$ gram is $1000000000$ or ${{10}^{-9}}$ grams or centigrams. To acquire the conversion of grams to nanograms we just need to know that:
$1\text{ }nano\text{ }grams=1\times {{10}^{-9}}grams$ and
$1grams\text{ }=\text{ }1\times {{10}^{9}}\text{ }nano\text{ }grams$
Nano grams is a metric system mass unit. $1ng=1\times {{10}^{-9}}grams$ . The symbol is $ng$ .

Complete Step By Step Answer:
Firstly we should know the concept of conversion factor by term conversion factor we mean that formula which is applied to change one set of units to another that is formula which is required to convert a given measurement from one unit to the other by either multiplying or by dividing with given statement.
By conversion factor:
$5.67ng\left( \dfrac{1g}{1\times {{10}^{9}}ng} \right)=5.67\times {{10}^{-9}}g$ .

Additional Information:
So for further conversion we can easily do it with the help of this table :

If we have this	So we have to do this	So that we get this
milligrams (mg)	Divide by $10\text{ }\left( \dfrac{mg}{10} \right)$ Move Decimal one place to Left	centigram (cg)
centigrams (cg)	Multiply by $10\text{ }\left( cg\times 10 \right)$ Move decimal one place to the right	Milligrams (mg)
Grams (g)	Multiply by $100\text{ }\left( g\times 100 \right)$	Centigrams (cg)
Centigrams (cm)	Divide by $100\text{ }\left( \dfrac{g}{100} \right)$ Move decimal two places to the left.	Grams (g)
Milligrams (mg)	Divide by $1000\text{ }\left( \dfrac{mg}{1000} \right)$ Move decimal three places to the left.	Grams (g)

Note :
Note unit ng will be cancelled out and we'll get our product with grams in unit. Conversion factors are required because while doing the numerical we have different values in different units and while doing the calculation all the units should be the same, so we have to either multiply or by dividing the given value with unit of conversion value so that to convert their unit from one form to another vice versa.
