Benchmark(s) Addressed in Lesson

M.5.13 Convert fluently, between measurement systems (metric, customary, time), from one unit to another in

order to solve contextual problems and express the conversions using appropriate unit labels.

Materials:

Conversion Chart and Instructions, Conversion Practice Problems

Learner Prior Knowledge:

Some familiarity with traditional and metric liquid measurement would help students.

Activities

Step 1 Ask students if they know how much liquid they drink over the course of a day. What unit of measure do

they typically use? Allow for discussion of the health benefits of drinking plenty of fluids (better energy level, joint

lubrication, kidney stone prevention, constipation prevention, cold/flu remediation, replenishment of water lost

through exercise, etc.) Discuss symptoms of dehydration (excessive thirst, fatigue, headache, dry mouth, little or

no urination, muscle weakness, dizziness, lightheadedness). Discuss how excessive thirst and frequent urination

can be indicators of underlying disease such as diabetes. Ask for examples of people who may need to increase

fluid intake (athletes, breast-feeding women). Ask for examples of people whose fluid intake might be restricted

(those with kidney disease or congestive heart failure).

Step 2 Explain that for some of the reasons discussed above, nurses may often be required to monitor the fluid

intake of their patients. Because US products are usually measured in ounces, and nursing records require metric

measurements, they will need to know how to convert from fluid ounces to milliliters.

Step 3 Distribute Conversion Chart and Instructions, and discuss with students. Be sure they understand

how the answers in the sample conversions were reached.

Step 4 Distribute Conversion Practice Problems. Allow students to work independently, giving assistance

where needed.

Step 5 Check work and provide further instruction if needed.

Assessment/Evidence:

Student will successfully complete Conversion Practice Problems.

Converting Fluid Ounces to Milliliters (Cubic Centimeters)

As a nurse, you may be required to keep track of a patient’s fluid intake. Since

most products in the United States are sold by the fluid ounce, and nursing

documentation requires charting fluid intake bymilliliters (mLs), also known as

cubic centimeters (CCs), you will need to convert liquid measures from fluid

ounces to their metric equivalents. The chart below gives you equivalents for

commonly used fluid measurements.

US liquid Measurements and Metric Fluid Measures

U.S. Liquid Metric

1 drop = .06 milliliter (ml)

15 drops = 1 milliliter (ml)

1 teaspoon (tsp) = 5 milliliters (ml)

1 tablespoon (Tbsp) = 15 milliliters (ml)

1 ounce (oz) = 30 milliliters (ml)

1 cup (c) = 240 milliliters (ml)

1 pint = 480 milliliters (ml)

1 quart = 960 milliliters (ml)

4 cups (c) = 960 milliliters (ml)

Sample conversions:

If you know the approximate number of ounces a patient has had, simply multiply

by 30 to get the number of mLs (CCs) a patient has taken in.

If a patient drinks an 8-ounce beverage (one cup) he has ingested 240 milliliters or

cubic centimeters.

If a patient has had 2/3 of a 20-ounce water bottle, she has had 2/3 x 20 ounces, or

about 13.3 ounces. One ounce is 30 milliliters, so multiply 13.3 times 30. The

patient has had 399, or about 400 ounces.

Conversion Practice Problems

The following word problems give practice in converting a patient’s fluid intake

from ounces to milliliters (mLs), also known as cubic centimeters (CCs).

1. Lisa drank a 4-ounce apple juice. How many milliliters did she drink?

2. Joey drank a half-pint carton of chocolate milk. How many mLs did he drink?

3. Mr. Ramirez drank about three fourths of his 20-ounce water bottle. What was

his fluid intake in cubic centimeters?

4. With his lunch, Stephen had half a 10 ounce can of broth and a 12-ounce can of

Coca-Cola. How many CCs did he drink?

5. At breakfast, Mrs. Phelps used about two thirds of her 8-ounce milk on her

cereal. She drank all of her 4-ounce cranberry juice and about half her 6-ounce cup

of tea. How many CCs of liquid did she have?

6. Mrs. Gray drank about half an 8-ounce bottle of Ensure and a couple of

tablespoons of water. In milliliters, what was her fluid intake?

7. At supper, Mr. Geiger had a half a cup of broth, a 6-ounce coffee, 4 ounces of

grape juice, and one fourth of a 20-ounce water bottle. How many cubic

centimeters of liquid did he take in?
