Compare and Convert Metric Units of Volume

Conversions of common metric units of volume:

1 liter = 1,000 milliliters

1 milliliter = 1 1,000   liter

Let's consider an example.

Suppose we need to compare 31 liters and 32,200 milliliters.

In order to compare, we first convert 31 liters to milliliters.

We know that 1 liter is equal to 1,000 milliliters.

We need to multiply 1,000 by 31 to know the number of milliliters in 31 liters.

1,000 × 31 = 31,000

So, 31 liters = 31,000 milliliters

Now, 31,000 milliliters is less than 32,200 milliliters.

So, 31 liters < 32,200 milliliters.
