Question

How do you convert mg to g?

Answer 1

Hint: We all know the basic conversion that is $1$ Milligram (mg) is equal to $$0.001$$ gram (g). To acquire the conversion of milligrams to grams we just need multiply the milligram value by $$0.001$$ or by simply divide it by $$1000$$
Milligram is a metric system mass unit. $$1mg=0.001g$$ The symbol is "mg".
For example, to convert $70$ mg to grams, multiply $70$ by $$0.001$$ that makes $$0.07$$ gram is $70$ mg.
milligrams to grams formula :
$$gram=milligram\times 0.001$$
$$gram={\displaystyle \frac{milligram}{1000}}$$
$$1Milligram=0.001Gram$$

Complete answer:
Firstly we should know the concept of conversion factor by the term conversion factor we mean that the formula which is applied to change the one set of units to another that is formula
which is required to convert a given measurement from one unit to the another by either multiplying or by dividing with the given statement.
$$1milligram\left(mg\right)$$ which is equal to $${\displaystyle \frac{1}{1000grams}}$$
$$1mg=\left({\displaystyle \frac{1}{1000}}\right)g=0.001g$$
The mass in grams (g) which is equal to the mass in milligrams (mg) it is divided by $1000$
$$m\left(g\right)={\displaystyle \frac{m\left(mg\right)}{1000}}$$
Example we have to convert $$15mg$$ to grams:
$$m\left(g\right)={\displaystyle \frac{15mg}{1000}}=0.015g$$

Note: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.
