About Milliliter (mL)
Definition
The milliliter is a unit of volume equal to one thousandth of a liter (10⁻³ L), exactly equal to one cubic centimeter.
Mathematical Relationship
1 mL = 10⁻³ L = 1 cm³ = 1 cc = 1,000 µL. There are 1,000 mL in one liter.
Conversion Formula
To liters: divide by 1,000. To fluid ounces (US): multiply by 0.033814. To teaspoons (US): multiply by 0.202884.
Practical Applications
Medicine dosing, cooking measurements, beverage volumes (e.g., 330 mL soda can), and cosmetic product sizing.
Interesting Facts
A standard soda can holds 330–355 mL. A shot glass holds about 44 mL. One mL of water weighs exactly 1 gram at 4 °C.
Common Mistakes
Confusing mL with mg (volume vs. mass). Also, 1 mL of oil or alcohol does NOT weigh 1 gram — only water does (at 4 °C).
Educational Tips
1 teaspoon ≈ 5 mL, 1 tablespoon ≈ 15 mL. These are the best kitchen anchors. A standard medicine syringe holds 5 mL.
