# How many milligrams in a 1.36*g mass?

$1 \cdot g \equiv 1000 \cdot m g$........
The prefix $\text{milli}$ $\equiv$ $\times {10}^{-} 3$
And thus $1 \cdot g \equiv {10}^{3} \cdot m g$.
So a $1.36 \cdot g$ mass $\equiv$ $\frac{1.36 \cdot \cancel{g}}{{10}^{-} 3 \cdot \cancel{g} \cdot m {g}^{-} 1} = 1360 \cdot m g$
