In order to pass from milliliters to liters we have to consider that 1 liter is equivalent to 1000 mL, then we can formulate the following conversion factor:
[tex]\frac{1L}{1000mL}[/tex]Then, in order to convert the given amount from milliliters to liters we just have to multiply for this factor to get:
[tex]30000mL\times\frac{1L}{1000mL}=\frac{30000}{1000}L=30L[/tex]Then, the capacity is 30 L
