Question

How many milligrams in $9$ grams?

Answer 1

Hint: Here the grams and the milligrams both are the unit of weight. To convert from grams to milligrams we can make use of a formula given by $milligram=grams\times 1000$. By substituting the value they have given in the question in place of gram we can get the correct answer in terms of grams.

Complete step by step answer:
Gram and the milligram both are the units of weight. Other than these we have kilograms, micrograms, nanograms, and many more.
In order to represent gram, we make use of a symbol ‘g’, whereas for milligram the symbol is ‘mg’.
Here they have asked us to convert gram to the milligram.
To convert gram to milligram we can make use of the formula which is given by:
$milligram=grams\times 1000$ this can also be written as
$grams={\displaystyle \frac{milligram}{1000}}$ .
Now, to convert $9$ grams to milligrams, we need to substitute $9$ in the place of a gram in any one of the above equations.
Therefore, on substitution we get
$milligram=9\times 1000$
So on simplifying the above expression, we get
$milligram=9000$.

Therefore the $9$ grams is equal to $9000$ milligrams.

Note:
Whenever they ask you to convert from one unit of weight to another unit of weight, first we need to know the conversion formula. If we do not know the conversion formula we are not able to get the correct answer. They may give only the symbol of the unit to confuse sometimes, so try to remember the symbols as well. If you know that $1$ gram is equal to $1000$ milligram then you can directly get the answer.
