Liters and Mililiters interactive worksheet - Free Printable

Let's solve this step-by-step. The task is to choose the proper unit of capacity — either litre (L) or millilitre (mL) — for each object shown in the image.

---

🔍 Understanding the Units:

- 1 litre (L) = 1000 millilitres (mL)
- Litres are used for larger amounts of liquid.
- Millilitres are used for smaller amounts of liquid.

Now, let’s go through each object:

---

1. Milk (Carton)

- A typical milk carton holds 1 litre or more (e.g., 1 L, 2 L).
- ✔ Answer: Litre

---

2. Can (Soda Can)

- A standard soda can holds about 330 mL or 355 mL.
- This is a small amount, so it's measured in millilitres.
- ✔ Answer: Millilitre

---

3. Pitcher

- A pitcher usually holds 1 litre or more (like 2 L), used for serving water or juice.
- ✔ Answer: Litre

---

4. Backpack

- A backpack is not a container for liquids — but if we're thinking about how much liquid it could carry, it might hold a few litres (e.g., water bottles).
- However, since it's not a liquid container, and the question likely refers to capacity for liquids, a backpack would hold several litres (like 1–5 L).
- But note: backpacks aren't measured in millilitres because they’re too large.
- ✔ Answer: Litre

5. Hand Soap Dispenser

- These are small bottles, typically holding 200 mL to 500 mL.
- Not big enough for a full litre.

7. Large Water Bottle

- A large water bottle might be 1.5 L, 2 L, etc.
- Definitely measured in litres.
- ✔ Answer: Litre

8. Juice Box

- A juice box is small — usually 200 mL to 250 mL.
- Commonly sold in millilitre quantities.
- ✔ Answer: Millilitre

| Can | Millilitre |
| Pitcher | Litre |
| Backpack | Litre |
| Hand Soap Dispenser | Millilitre |
| Jug | Litre |
| Large Water Bottle | Litre |
