# What is 3.36 liters in milliliters?

There are 1000 millilitres in a litre. So (3.36*cancel(L))xx(1000*mL*cancel(L^-1)) = ?? mL
The prefix "milli" means ${10}^{-} 3$. Thus 1 millilitre $=$ ${10}^{-} 3$ $L$. And thus when we ask how many millilitres in a litre we do the operation: $\frac{1 L}{m L}$, we do the mathematical operation, $\frac{1 L}{{10}^{-} 3 L}$ $=$ $1000$. Sometimes drugs are delivered in $\mu L$ doses. There are 1,000,000 $\mu L$ in $1$ litre (i.e. $1 L$ $=$ 10^6 muL); and therefore in a $m L$ (10^-3L), there are 1000 $\mu L$.
