5 liters how many milliliters
Understand the Problem
The question is asking to convert 5 liters into milliliters. We know that 1 liter is equal to 1000 milliliters, so we can perform a multiplication to find the answer.
Answer
$5000 \text{ milliliters}$
Answer for screen readers
The final answer is $5000 \text{ milliliters}$.
Steps to Solve

Identify the conversion factor
We need to convert liters to milliliters. The conversion factor is that $1 \text{ liter} = 1000 \text{ milliliters}$. 
Set up the multiplication
To find how many milliliters are in 5 liters, we will multiply the number of liters by the conversion factor. $$ \text{Milliliters} = 5 \text{ liters} \times 1000 \text{ milliliters/liter} $$ 
Calculate the result
Now we perform the multiplication: $$ \text{Milliliters} = 5 \times 1000 = 5000 $$ 
State the final result
We have calculated the total amount in milliliters.
The final answer is $5000 \text{ milliliters}$.
More Information
This conversion is quite useful in cooking, science experiments, and when measuring liquids, as milliliters are typically smaller units that allow for precise measurement.
Tips
 A common mistake is forgetting the multiplication by the conversion factor (1000). Always make sure to apply the conversion factor correctly.
