Us liquid measurements8/2/2023 ![]() It only applies for a liquid ounce in U.S. Note that this is a fluid ounce measuring volume, not the typical ounce that measures weight. It is exactly equivalent to 1 cubic centimetre (cm³, or, non-standard, cc). It is a non-SI unit accepted for use with the International Systems of Units (SI). The millilitre (ml or mL, also spelled milliliter) is a metric unit of volume that is equal to one thousandth of a litre. Ounce to milliliter, or enter any two units below: Enter two units to convert From: Understands formulas for finding measures (e.g.You can do the reverse unit conversion from Selects and uses appropriate units and tools, depending on degree of accuracy required, to find measurements for real-world problemsħ. Understands the concepts of precision and significant digits as they relate to measurement (e.g., how units indicate precision)Ħ. Solves problems involving units of measurement and converts answers to a larger or smaller unit within the same system (i.e., standard or metric)ĥ. Knows approximate size of basic standard units (e.g., centimeters, feet, grams) and relationships between them (e.g., between inches and feet)Ĥ. Selects and uses appropriate tools for given measurement situations (e.g., rulers for length, measuring cups for capacity, protractors for angle)ģ. Understands the basic measures perimeter, area, volume, capacity, mass, angle, and circumferenceĢ. Standard 4. Understands and applies basic and advanced properties of the concepts of measurementġ. A great visual way to reinforce this lesson on conversion would be to have students draw the following image in their notebooks.Model in a think-aloud fashion the process of determining the number of cups that are equal to a gallon (e.g., "We now know that there are four quarts in a gallon and there are four cups in a quart therefore, I need to multiply 4 x 4 to determine that there are 16 cups in a gallon.").After students have completed the conversion chart, have them share their answers and explain what math problems they had to solve in order to complete the chart.(Students may also need to be reminded that clicking on the "BACK" button in the upper left hand corner of the tool bar will return them to the previous display.)ĭetermining how many cups equal a gallon: Circulate around the room as students work, ensuring that students are clicking on each of the liquid units of measurement in order to see how each of the units is defined. ![]() Explain to students that it will often require multiplication to complete the chart if they are converting from a larger unit of measurement to a smaller one, they will need to multiply.Have students copy and complete the following chart in their notebooks by using the Visual Thesaurus interactive display of United States liquid units and their definitions.Ĭonverting to another unit of measurementġ fluid ounce = _cup (hint: this answer should be a fraction).Ĭonverting from one liquid unit of measurement to another: Look up the term United States liquid unit in the VT and reveal the different types of US liquid units contained in the Visual Thesaurus database by clicking on the red meaning bubble attached to the term or by clicking on the definition of United States liquid unit listed in the meaning list on the right side of the word map display.Display the Visual Thesaurus word map for gallon and point out the definition "United States liquid unit equal to four quarts?" and explain that the United States Customary System for measurement is different than the system nearly all other countries in the world use - the metric system.Then, they will be able to return to the problem having learned how many cups are in one gallon. Explain to the class that in order to solve the problem in the warm up, students will need to first figure out how all the different units relate to one another in the US system for measuring liquids.Introducing the US Customary System of measurement:
