Measure Volume
Measure capacity in metric units.
Liter (L) and milliliter (mL) are metric units of capacity.
This water bottle holds 1 liter of water.
This dropper holds 1 milliliter of liquid.
Let's Practice Together
Choose the better estimate for the capacity of each.
1.
3 L 30 mL
2.
1 L 10 L
3.
14 L 40 mL
Your Turn
Choose the unit (mL or L) you would use to measure the capacity of each.
4. a bathtub
5. a spoon
6. a container of milk
7. a pail
8. a soup can
9. a drinking glass
10. a pond
11. a sink
12. a watering can
Check for Understanding
1. Would you need a larger container to hold 500 mL or to hold 1 L? Explain.
2. Jan poured 4 liters of water into a pot. How many milliliters of water did she pour into the pot?
3. A baby whale calf should drink 300 liters of milk each day. Is 30,000 mL of milk enough to feed a baby whale calf for one day?
Answers
1. 3 L
2. 1 L
3. 40 mL
4. L
5. mL
6. L
7. L
8. mL
9. mL
10. L
11. L
12. L
Check for Understanding
1. 1 L, because 1 L is the same as 1000 mL, and 1000 > 500
2. 4,000 mL
3. No, 30,000 mL is only 30 L.
