How Do I Convert 1/3 Cup to mL?

Quick explanation

Use this page when a recipe calls for 1/3 cup and you want one clear mL value instead of working from a fraction. The direct answer is about 83.3 mL in Metric mode or 78.9 mL in US mode. This amount shows up often in sauces, milk, oil, and sugar, where a quick mL target is easier to measure than repeating a fraction.

Calculation steps

How to convert 1/3 cup to mL exactly

mL = cups × cup-size-in-mL

For this page, cups = 0.333. Use 250 mL for Metric cup and 236.588 mL for US cup.

Practical kitchen rounding

1/3 cup ~ 83 mL (Metric) or 79 mL (US)

Nearest 1 mL is usually sufficient for daily cooking; stay on one cup standard through the recipe.

Worked example (this page)

Input: 0.333

Metric: 0.333 x 250 = 83.25 mL; US: 0.333 x 236.588 = 78.78 mL.

Practical: use 83 mL (Metric) or 79 mL (US).

About these units

Why cup values differ

Cup values vary by region, so 1/3 cup is not one universal mL result. Even at this smaller amount, the difference is worth checking when a recipe uses several cup fractions across the same batter or sauce.

Metric cup = 250 mL (common in metric-standard recipe sources).
US cup = 236.588 mL (common in US recipe sources).
At 1/3 cup, the gap is about 4.4 mL between standards.

Millilitre (mL)

mL is a metric unit useful for precise measuring jugs and consistent scaling. It helps turn a slightly awkward cup fraction into one clear number you can pour and repeat.

1000 mL = 1 liter.
mL outputs reduce ambiguity when sharing recipes across regions.
Around 80 to 83 mL is a common checkpoint for small liquid additions.

Tips

Quick check: 1 tsp = 5 mL and 1 tbsp = 15 mL (handy for medicine-cup style measuring too).

When scaling recipes, convert to metric first (mL/g), scale, then convert back if needed.

Handy shortcut: 1 tbsp = 3 tsp.
