If you’re converting sauces, rounding to the nearest 5 mL is usually fine.
How Do I Convert 1/2 Cup to mL?
Quick explanation
Use this page when a recipe calls for 1/2 cup and you want the matching mL total right away. The direct answer is 125 mL in Metric mode or about 118.3 mL in US mode. Because 1/2 cup shows up constantly in milk, oil, broth, sugar, and baking ingredients, it is one of the easiest places to drift if the wrong cup standard is used. For broader checks, use How Many mL Are in a Cup? or reverse the math with mL to Cups Converter.

Calculation steps
How to convert 1/2 cup to mL exactly
mL = cups × cup-size-in-mL
For this page, cups = 0.5. Use 250 mL for Metric cup and 236.588 mL for US cup.
Practical kitchen rounding
1/2 cup = 125 mL (Metric) or 118 mL (US)
Nearest 1 mL is usually sufficient for daily cooking; stay on one cup standard through the recipe.
Worked example (this page)
Input: 0.5
Metric: 0.5 x 250 = 125 mL; US: 0.5 x 236.588 = 118.29 mL.
Practical: use 125 mL (Metric) or 118 mL (US).
About these units
Why cup values differ
Cup values vary by region, so 1/2 cup is not one universal mL result. Because 1/2 cup is such a common amount, this is also one of the easiest places to accidentally switch standards without noticing.
- Metric cup = 250 mL (common in metric-standard recipe sources).
- US cup = 236.588 mL (common in US recipe sources).
- At 1/2 cup, the gap is about 6.7 mL between standards.
Millilitre (mL)
mL is a metric unit useful for precise measuring jugs and consistent scaling. For a common amount like 1/2 cup, it is often easier to pour once to the mL mark than to second-guess whether you are using the right cup standard.
- 1000 mL = 1 liter.
- mL outputs reduce ambiguity when sharing recipes across regions.
- 125 mL is an easy checkpoint on many measuring jugs.
Tips
If a conversion looks “off,” check whether you mixed weight (oz) and volume (fl oz).
Dry measuring cups and liquid measuring cups can read differently; both can be correct.
