Metric Units of capacity conversion Formulas

An object can be described in terms of its physical quantities, such as height, weight, mass, volume, size, shape, and so on. To quantify the physical quantities, units of measurement are used. We have a specific system of measurement for each quantity, with  two types of systems currently being used all over the world. One is the metric system, and the other is the customary system. Here we will focus on the metric system for measurement of capacity and its unit conversions....Read MoreRead Less

Defining Capacity

Capacity is the measure of the maximum quantity of liquid, or any pourable substance, which can be filled in a particular container. The term “volume” is also used to express capacity. The units of capacity used in the metric system are liter and milliliter


We can convert milliliters into liters by multiplying them by \(\frac{1}{1000}\)


We can convert liters into milliliters by multiplying them by 1000. The conversion of units helps us express a quantity in different units.

Units of capacity conversion formula

The formulas used to convert units of capacity are:


  • 1 liter = 1000 milliliters (ml)


  • 1 milliliter = \(\frac{1}{1000}\) liters

How can we use the units of capacity conversion formula?




Let us understand the concept visually. If you take a liter of water and fill it equally into 1000 containers, the quantity of water in each container will be 1 milliliter. 


1 liter (l) = 1000 milliliters (ml)

1 milliliter (ml) = \(\frac{1}{1000}\) liters (l)


To convert from a larger unit to a smaller unit, we need to multiply. 


If we have “a” liters of liquid, this quantity in milliliters will be:


(a x 1000)ml, that is, we multiply by 1000.


Conversely, to convert from a smaller unit to a larger unit, we need to divide. 


If we have “b” milliliters of liquid, this quantity in liters will be:


\(\frac{b}{1000}\) liters, that is, we divide by 1000.


Rapid Recall: 


1 liter = 1000 milliliters (ml)


1 milliliter = \(\frac{1}{1000}\) liters

Solved Examples

Example 1: Convert 11 liters into milliliters.




We know that there are 1000 milliliters in 1 liter.


11 liters = (11 x 1000) milliliters       [Unit conversion formula]


             = 11000                             [Multiply]


So, there are 11000 milliliters in 11 liters.



Example 2: Convert 460 milliliters into liters.




We know that there are \(\frac{1}{1000}\) liters in 1 milliliter.


460 milliliters = ( 460 x \(\frac{1}{1000}\) ) liters            [Unit conversion formula]


                       = 0.46                                  [Simplify]


So, 460 milliliters is 0.46 liters.



Example 3: How many milliliters are there in 623 liters?


Solution : 


We know that there are 1000 milliliters in 1 liter.


\(6\frac{2}{3}\) liters 


= ( 6 +\(\frac{2}{3}\) ) liters 


= ( 6 + \(\frac{2}{3}\) )1000 milliliters               [Unit conversion formula]


= 6 x 1000+\(\frac{2}{3}\) x 1000 milliliters     [Distributive property]


= 6000+ \(\frac{2000}{3}\) milliliters                 [Multiply]


= \(\frac{18000+2000}{3}\) milliliters                    [Simplify]


= \(\frac{20000}{3}\) milliliters                            [Add]


= \(6666\frac{2}{3}\) milliliters           


So, there are \(6666\frac{2}{3}\) milliliters in \(6\frac{2}{3}\) liters.



Example 4: How many liters are there in \(8502\frac{6}{7}\) milliliters?




We know that there are \(\frac{1}{1000}\) liters in 1 milliliter.


How many liters are present in \(8502\frac{6}{7}\) milliliters? 


= ( 8502 + \(\frac{6}{7}\) )milliliters


= (8502+\(\frac{6}{7}\) ) x \(\frac{1}{1000}\)  liters              [Unit conversion formula]


= 8502 x \(\frac{1}{1000}\)+\(\frac{6}{7}\) x \(\frac{1}{1000}\) liters       [Distributive Property]


= \(\frac{8502}{1000}\) + \(\frac{6}{7000}\)  liters                       [Multiply]


= \(\frac{59514+6}{7000}\)  liters                             [Simplify]


= \(\frac{59520}{7000}\) liters                                  [Add]


\(\approx\) 8.50 liters


So, there are about 8.50 liters in \(8502\frac{6}{7}\) milliliters.



Example 5: John orders 5 cans of milk from a supermarket. The capacity of each can is 2.5 liters. What is the total quantity of milk John ordered from the supermarket in milliliters?


Solution :


John orders 5 cans of milk, each with a capacity of 2.5 liters.


So, he orders a total of 5 x 2.5 = 12.5 liters.


Now we have to convert 12.5 liters into milliliters


We know that there are 1000 milliliters in 1 liter.


12.5 liters


= 12.5 x 1000 milliliters           [Unit conversion formula]


= 12500 milliliters                   [Multiply]


So, John orders 12500 milliliters of milk from the supermarket.
