How To Understand Measurements

Units of measure are sometimes confusing so we will review some basics.

When in doubt, take a moment to review facts online – there are plenty of references which will explain each unit of measure clearly and also offer free conversion charts!



What is a mL?

  • ML refers to milliliter.
  • This is a unit of volume, used when measuring liquids.
  • Everyone has seen “1 GALLON, 3.79 LITERS” on a bottled water label.
  • Similar content summaries will be available on every liquid we drink or use in every day life.
  • One mL is 1/1000 of a liter.


What about CC?

CC stands for “cubic centimeter” and is equal to one mL.  Both are used for measurements of volume and can be used interchangeably.



Is an ounce the same as a mL?


1 Ounce (fl oz or fluid ounce) = 29.57mL in the US system, so 1oz=30mL roughly




What about mg?

  • A milligram is a unit of weight.  Some people weigh their food, ingredients, or herbal supplements.
  • A “mg” is 1/1000 of a gram
  • A milligram can equal 1000 micrograms, 0.001gram
  • A microgram or mcg < mg



In Summary:

1000mL (milliliter) = 1 L (liter)

29.57mL = 1 Ounce

1mL = 1/1000 of a liter or 5 teaspoons

1mL = 1CC


Unit of Weight

1000 g (gram) = 1 kg (kilogram)

1000 mg (milligram) = 1 g
