How Much is 1 Milliliter? Definition and Examples

A milliliter (abbreviated as "ml") is a unit of capacity or volume in the metric measurement system that is equal to one thousandth of a liter.

1 milliliter  = (1/1000) liter or 1 liter = 1000 milliliters

The milliliter is used to measure things that have small volumes

Things That Can Have a volume of Approximately 1 Milliliter

  • About 20 drops of water
  • About one-fifth of a teaspoon of water
  • About one-third the volume of water inside a straw that has a diameter of about 0.4 centimeter and a height of about 24 centimeters.

How water can you put inside a straw?

To calculate the volume of water inside a straw, we can use the straw shown below that has a diameter of about 0.4 centimeters and a height of about 24 centimeters.

1 milliliter of water

We need to use the formula to find the volume of a cylinder since the straw is a cylinder.

r = 0.4/2 = 0.2

Volume = 3.14 × (0.2)2 × 24

Volume = 3.14 × 0.04 × 24

Volume = 3.14 × 0.96 = 3.0144 cm3

The volume is about 3 milliliters

Therefore, if the straw is one-third full, there is approximately 1 milliliter of water. This is illustrated above!
