How many ml does a 1 2 cup have?

When it comes to measuring ingredients for cooking and baking, it’s important to understand the different units of measurement for volume and how to convert between them. Two common units for measuring volume in the kitchen are cups and milliliters (ml). So how many ml are in 1⁄2 cup? Let’s take a closer look.

What is a Cup?

A cup is a standard unit of measurement used in cooking and baking in the United States. One cup is equal to 8 fluid ounces or 16 tablespoons. Cup measurements are most often used for volumes of liquid ingredients like water, milk, or oil. They are also used for solid ingredients like flour, sugar, oatmeal, etc.

There are a few key things to understand about cup measurements:

  • 1 cup = 8 fluid ounces = 16 tablespoons
  • 1⁄2 cup = 4 fluid ounces = 8 tablespoons
  • 1⁄4 cup = 2 fluid ounces = 4 tablespoons
  • Cup measurements are most often used for liquid and solid ingredients in recipes
  • Standard measuring cups are available in 1 cup, 1⁄2 cup, 1/3 cup, 1⁄4 cup and smaller sizes

What is a Milliliter?

A milliliter (ml) is a metric unit of measurement for volume. 1000 ml make up 1 liter. Milliliters are commonly used for measuring volumes of liquids in metric recipes.

Here are some key facts about ml measurements:

  • 1 ml = 0.001 liter
  • 1000 ml = 1 liter
  • Milliliters are used for measuring liquids and fluids
  • Common lab equipment like beakers, flasks, and cylinders are marked with milliliter measurements

Converting Between Cups and Milliliters

Since cups and milliliters are both units for measuring volume, we can convert between them using a simple formula:

1 cup = 236.588 ml

This conversion accounts for the different size of cup measurements vs. metric milliliters. Knowing this conversion allows us to calculate ml amounts from cup measurements and vice versa.

For example:

  • 1 cup = 236.588 ml
  • 1⁄2 cup = 118.294 ml (half of 236.588 ml)
  • 1⁄4 cup = 59.147 ml (half of 118.294 ml)

So if you need to know how many ml are in 1⁄2 cup, the conversion would be:

1⁄2 cup = 118.294 ml

Converting Other Common Cup Measurements to Milliliters

Using the cups to ml conversion, we can calculate how many ml are in other fractional cup measurements:

Cup Measurement Milliliters
1 cup 236.588 ml
3⁄4 cup 177.441 ml
2⁄3 cup 157.725 ml
1⁄2 cup 118.294 ml
1⁄3 cup 78.529 ml
1⁄4 cup 59.147 ml

Tips for Accurately Measuring Cups and Milliliters

When measuring ingredients for cooking and baking, be sure to accurately measure out amounts for the best results:

  • Use standard, liquid measuring cups for cup measurements of liquids like milk, water, oil, etc.
  • Use dry measuring cups for solid ingredients like flour, sugar, oatmeal, etc. Scoop ingredients and level off the top.
  • When measuring ml amounts, use a clear liquid measuring cup with ml markings for accuracy.
  • To measure small ml amounts, use a plastic syringe or pipette for precision.
  • Don’t substitute cup measurements for ml amounts or vice versa unless you do the conversion.

Converting Milliliters to Cups

You can also convert milliliter amounts to cup measurements using the same ratio:

236.588 ml = 1 cup

To convert ml to cups:

  1. Take the ml amount and divide by 236.588.
  2. This will give you the number of cups.

For example, to convert 500 ml to cups:

500 ml ÷ 236.588 = 2.11 cups

So 500 ml is equivalent to approximately 2 1⁄8 cups. Let’s look at some other common conversions:

Milliliters Cups
118.3 ml 1⁄2 cup
236.6 ml 1 cup
355 ml 1 1⁄2 cups
473 ml 2 cups

Tips for Converting Between Cups and Milliliters

Here are some useful tips when converting measurements between cups and milliliters:

  • Memorize the basic conversion: 1 cup = 236.588 ml
  • When converting a mixed number of cups to ml, convert the whole number first, then add the fractional part.
  • For ml amounts, divide by 236.588 and round to the nearest cup measurement.
  • Mark a measuring cup or pitcher at the 236 ml line for easy reference.
  • To convert when cooking, use the conversions at left and your ingredients list.

Common Conversions

For quick reference, here are some of the most common conversions between cups measurements and milliliters:

Cups Milliliters
1 cup 236.6 ml
3⁄4 cup 177 ml
2⁄3 cup 158 ml
1⁄2 cup 118 ml
1⁄3 cup 79 ml
1⁄4 cup 59 ml

Having a handy reference for these conversions can help make measuring ingredients and converting amounts a breeze!

Converting Other Common Cooking Measurements

In addition to cups and milliliters, there are some other handy cooking conversions to know:

  • 3 teaspoons (tsp) = 1 tablespoon (tbsp)
  • 2 tablespoons = 1 fluid ounce
  • 16 tablespoons = 1 cup
  • 1 pound (lb) butter = 2 cups
  • 1 pint (pt) = 2 cups
  • 4 cups = 1 quart (qt)
  • 4 quarts = 1 gallon (gal)
  • 1 liter (L) = 1.06 quarts
  • 240 ml = 1 cup
  • 1 fluid ounce = 30 milliliters

Handy Conversions When Cooking

Having some common cooking conversions memorized or readily available can make measuring and converting a breeze when cooking and baking. No more hunting around for a calculator or conversion chart!

Here are some of the handiest conversions to know:

  • 3 tsp = 1 Tbsp
  • 4 Tbsp = 1⁄4 cup
  • 5 Tbsp + 1 tsp = 1⁄3 cup
  • 8 Tbsp = 1⁄2 cup
  • 16 Tbsp = 1 cup
  • 2 cups = 1 pint
  • 2 pints = 1 quart
  • 4 quarts = 1 gallon
  • 1 cup = 237 ml

Having these committed to memory can make a big difference in being able to easily adapt recipe measurements and convert between units.

Why Accurate Measurement Matters

When baking recipes and preparing ingredients, accurate measurement is key for getting good results. Here are some reasons why measuring ingredients precisely matters:

  • Ratios matter – Many baked goods rely on the right ratios of flour, liquid, leavening, eggs, etc.
  • Consistency – Accurate measuring leads to consistent results each time you make a recipe.
  • Volume – Precise cup, tbsp, tsp ensure you get the right volume and yield.
  • Rising and texture – Measurements impact how doughs, batters and mixtures come together and rise.
  • Flavor balance – Getting measurements right means flavors stay in balance and aren’t too concentrated.
  • Food safety – Improperly measured wet or dry ingredients can create food safety issues.

While small variations in measuring won’t make or break most recipes, striving for precision will give you the best shot at baking success!


So in summary, the answer to “How many ml are in 1⁄2 cup?” is 118.3 ml. Knowing the basic conversions between cups and milliliters allows you to translate cooking amounts between these common volume measurements.

Some key takeaways:

  • 1 cup = 236.6 ml
  • 1⁄2 cup = 118.3 ml
  • Divide ml by 236.6 to get cups
  • Memorize some handy conversions like cups to tablespoons
  • Use proper measuring tools for liquid vs. dry ingredients
  • Accurate measuring leads to better results in baking

Having a good understanding of metric and cup measurements, how to convert them, and when to use each in the kitchen helps ensure success with recipes. So measure precisely, know your conversions, and enjoy delicious baking results!
