Summary
Grade 6-8 students learn how to convert temperatures between Fahrenheit and Celsius using two formulas: C = (F − 32) × 5/9 and F = C × 9/5 + 32. The lesson works through a full example in each direction (68°F to 20°C, and 25°C to 77°F), and grounds the concept with key reference points — the freezing point, boiling point, and normal body temperature on both scales.
Student Worksheet: Converting Between Fahrenheit and Celsius
Teacher Note: Students can watch the video lesson above and answer the questions. Click the “Teacher Answer Key” dropdown below when you are ready to review the solutions!
Key Concepts:
• Fahrenheit to Celsius: C = (F − 32) × 5/9 — subtract 32 first, then multiply by 5/9.
• Celsius to Fahrenheit: F = C × 9/5 + 32 — multiply by 9/5 first, then add 32.
• Key Reference Points: Water freezes at 32°F (0°C), body temperature is about 98.6°F (37°C), and water boils at 212°F (100°C).
Instructions: Read each question carefully and write your answer in the space provided.
- Question 1: Convert 68°F to Celsius.
- Question 2: Convert 25°C to Fahrenheit.
- Question 3: What is the correct order of steps when converting Fahrenheit to Celsius?
- Question 4: At what Fahrenheit temperature does water freeze? What is that in Celsius?
- Question 5: Convert 100°F to Celsius (round to the nearest whole degree).
- Question 6: Convert 0°C to Fahrenheit.

1. 20°C (68 − 32 = 36, 36 × 5/9 = 20)
2. 77°F (25 × 9/5 = 45, 45 + 32 = 77)
3. Subtract 32 first, then multiply by 5/9.
4. 32°F, which is 0°C.
5. About 38°C (100 − 32 = 68, 68 × 5/9 ≈ 37.8, rounds to 38)
6. 32°F (0 × 9/5 = 0, 0 + 32 = 32)
