In cooking, sometimes recipes call for milliliters of some ingredient. Milliliters are in the metric system. Sometimes all you have are measuring cups and measuring spoons that don’t have the milliliter cooking measurement.
To convert 40 ml to cups, you can simply use 1/6 cup as a substitute. This way, you can use your existing measuring cup for the recipe you plan on making. To convert ml to cups, you can take the number of milliliters and divide by 237. So 40 ml divided by 237 approximately equals 1/6 cup.
Some measuring cups and measuring spoons also show cooking measurements for fluid ounces. To convert 40 ml to oz, you can use 1 1/3 oz as a substitute. To convert ml to oz, you divide the number of milliliters by 30. So 40 ml divided by 30 is approximately 1 1/3 oz.
