example 40: how many kilograms are there in 45,436 mg?
Answer
Explanation:
Step1: Recall conversion factors
We know that $1\ g = 1000\ mg$ and $1\ kg=1000\ g$. So $1\ kg = 1000\times1000\ mg= 10^{6}\ mg$.
Step2: Convert milligrams to kilograms
To convert $45436\ mg$ to $kg$, we use the formula $kg=\frac{mg}{10^{6}}$. So, $\frac{45436}{10^{6}}=0.045436\ kg$.
Answer:
$0.045436$
