Printable worksheet featuring various temperatures in Celsius for students to convert into Fahrenheit.

To convert temperatures from Celsius (°C) to Fahrenheit (°F), we use the following formula:

$$
°F = \left( \frac{9}{5} \times °C \right) + 32
$$

Let’s go through each conversion step by step.

---

1. $-11^\circ C$

$$
°F = \left( \frac{9}{5} \times -11 \right) + 32 = (-19.8) + 32 = 12.2^\circ F
$$

✔ Answer: 12.2°F

---

2. $3^\circ C$

$$
°F = \left( \frac{9}{5} \times 3 \right) + 32 = 5.4 + 32 = 37.4^\circ F
$$

✔ Answer: 37.4°F

---

3. $-18^\circ C$

$$
°F = \left( \frac{9}{5} \times -18 \right) + 32 = (-32.4) + 32 = -0.4^\circ F
$$

✔ Answer: -0.4°F

---

4. $15^\circ C$

$$
°F = \left( \frac{9}{5} \times 15 \right) + 32 = 27 + 32 = 59^\circ F
$$

✔ Answer: 59°F

---

5. $2^\circ C$

$$
°F = \left( \frac{9}{5} \times 2 \right) + 32 = 3.6 + 32 = 35.6^\circ F
$$

✔ Answer: 35.6°F

---

6. $-34^\circ C$

$$
°F = \left( \frac{9}{5} \times -34 \right) + 32 = (-61.2) + 32 = -29.2^\circ F
$$

✔ Answer: -29.2°F

---

7. $-36^\circ C$

$$
°F = \left( \frac{9}{5} \times -36 \right) + 32 = (-64.8) + 32 = -32.8^\circ F
$$

✔ Answer: -32.8°F

---

8. $-3^\circ C$

$$
°F = \left( \frac{9}{5} \times -3 \right) + 32 = (-5.4) + 32 = 26.6^\circ F
$$

✔ Answer: 26.6°F

---

9. $-38^\circ C$

$$
°F = \left( \frac{9}{5} \times -38 \right) + 32 = (-68.4) + 32 = -36.4^\circ F
$$

✔ Answer: -36.4°F

---

10. $0^\circ C$

$$
°F = \left( \frac{9}{5} \times 0 \right) + 32 = 0 + 32 = 32^\circ F
$$

✔ Answer: 32°F

---

11. $-33^\circ C$

$$
°F = \left( \frac{9}{5} \times -33 \right) + 32 = (-59.4) + 32 = -27.4^\circ F
$$

✔ Answer: -27.4°F

---

12. $-40^\circ C$

$$
°F = \left( \frac{9}{5} \times -40 \right) + 32 = (-72) + 32 = -40^\circ F
$$

✔ Answer: -40°F
*(Note: -40°C = -40°F — this is the point where both scales are equal.)*

---

13. $22^\circ C$

$$
°F = \left( \frac{9}{5} \times 22 \right) + 32 = 39.6 + 32 = 71.6^\circ F
$$

✔ Answer: 71.6°F

---

14. $-18^\circ C$ (again)

We already did this one above:
$$
°F = (-32.4) + 32 = -0.4^\circ F
$$

✔ Answer: -0.4°F
