How do you convert a delta temperature from Celsius to Fahrenheit?

• A. ΔF = ΔC + 32
• B. ΔC = 1.8 × ΔF
• C. ΔF = 1.8 × ΔC
• D. ΔF = 2 × ΔC

Answer: (C)

When you’re converting a temperature difference between Celsius and Fahrenheit, you use the scaling factor 9/5 (1.8) and you ignore the 32-degree offset. The 32-degree offset only applies when converting actual temperatures, not changes. So the change in Fahrenheit is simply ΔF = (9/5)ΔC = 1.8 × ΔC. For example, a 5°C change corresponds to a 9°F change. The other options either try to add the offset or use an incorrect factor, which doesn’t reflect how differences scale between the two scales.
