Conversion Formula

To liters: multiply by 3.785. To UK gallons: multiply by 0.832674. To cubic meters: multiply by 0.003785.

Practical Applications

Fuel prices ($/gal), milk jugs, water cooler bottles, swimming pool chemicals, and paint quantities.

1 gallon ≈ 3.8 liters ≈ a large milk jug. 4 quarts = 1 gallon. A gallon of water weighs about 8.3 pounds.

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.
