Measuring Capacity: Liters and Milliliters
Practice choosing units, reading amounts, and solving capacity problems
Math - Grade 2-3
- 1
Circle the better unit to measure the amount of water in a bathtub: liters or milliliters. Explain your choice.
Use liters for larger amounts and milliliters for smaller amounts.
Liters are the better unit because a bathtub holds a large amount of water. - 2
Circle the better unit to measure the amount of medicine in a spoon: liters or milliliters. Explain your choice.
Milliliters are the better unit because a spoon holds a small amount of liquid. - 3
A bottle holds 1 liter of juice. How many milliliters of juice does the bottle hold?
Remember that 1 L = 1000 mL.
The bottle holds 1000 milliliters of juice because 1 liter equals 1000 milliliters. - 4
Mia has 500 mL of water in one cup and 300 mL of water in another cup. How much water does she have in all?
Mia has 800 milliliters of water in all because 500 mL + 300 mL = 800 mL. - 5
Which is more: 750 mL or 1 L? Explain how you know.
Change 1 L to milliliters before comparing.
1 liter is more because 1 liter equals 1000 milliliters, and 1000 mL is greater than 750 mL. - 6
A pitcher has 2 liters of lemonade. How many milliliters of lemonade are in the pitcher?
The pitcher has 2000 milliliters of lemonade because 2 liters equals 2000 milliliters. - 7
Sam pours 200 mL of milk into a glass. Then he adds 150 mL more. How much milk is in the glass now?
Add the two amounts of milk.
There are 350 milliliters of milk in the glass because 200 mL + 150 mL = 350 mL. - 8
A fish tank holds 10 liters of water. Would it be reasonable to say the tank holds 10 milliliters? Explain your answer.
No, it would not be reasonable because 10 milliliters is only a very small amount of water. A fish tank holds many liters. - 9
Look at a measuring jug filled to 600 mL. If 200 mL is poured out, how much liquid is left?
Subtract the amount poured out from the starting amount.
There are 400 milliliters left because 600 mL - 200 mL = 400 mL. - 10
Choose the best estimate for a small juice box: 2 mL, 200 mL, or 20 L. Explain your choice.
The best estimate is 200 mL because a small juice box holds more than a few drops but much less than many liters. - 11
Nora needs 1 liter of water for a recipe. She has 400 mL. How many more milliliters does she need?
First change 1 liter to 1000 milliliters.
Nora needs 600 more milliliters because 1000 mL - 400 mL = 600 mL. - 12
A watering can holds 3 L. A cup holds 250 mL. Which container holds more liquid? Explain your answer.
The watering can holds more liquid because 3 liters equals 3000 milliliters, which is greater than 250 milliliters. - 13
Put these amounts in order from least to greatest: 1 L, 250 mL, 750 mL.
Compare all amounts in milliliters.
The order from least to greatest is 250 mL, 750 mL, 1 L because 1 L equals 1000 mL. - 14
A classroom plant needs 500 mL of water each day. How much water does it need for 2 days?
The plant needs 1000 milliliters, or 1 liter, of water for 2 days because 500 mL + 500 mL = 1000 mL. - 15
A bucket has 5 L of water. After cleaning, 2 L are used. How many liters are left in the bucket?
Subtract the liters used from the liters in the bucket.
There are 3 liters left in the bucket because 5 L - 2 L = 3 L.
