What Fahrenheit range corresponds to the ideal 7–13°C storage temperature?

What Fahrenheit range corresponds to the ideal 7–13°C storage temperature?

• A. 60–70°F
• B. 45–55°F
• C. 32–40°F
• D. 70–80°F

Answer: (B)

Converting temperatures between Celsius and Fahrenheit is exactly what you’re doing here. Use F = C × 9/5 + 32. For 7°C: 7 × 9/5 = 12.6, plus 32 = 44.6°F. For 13°C: 13 × 9/5 = 23.4, plus 32 = 55.4°F. So 7–13°C corresponds to about 44.6–55.4°F, i.e., roughly 45–55°F. That range fits cool storage best, while the other options are clearly too warm or too cold.
