Scientific UseStandard in science and medicine worldwideRarely used in scientific contexts
Scale Intuition0 = freezing, 100 = boiling (logical)More granular for everyday weather (32-100 range)
Conversion Formula°C = (°F - 32) × 5/9°F = (°C × 9/5) + 32

✅ Celsius (°C)

Use Celsius in scientific, medical, and international contexts. It's the standard in virtually every country outside the United States and is the required unit in scientific research, medicine, and cooking in most of the world. The 0-100 scale between freezing and boiling makes it logically intuitive.

✅ Fahrenheit (°F)

Use Fahrenheit when communicating with American audiences or when working with US-based weather, cooking, or medical references. The larger scale (32-212 vs 0-100) provides more granularity for everyday temperature ranges, which some find useful for weather discussions.

Summary

Celsius is the global standard used by 95% of the world and all scientific disciplines. Fahrenheit is primarily used in the United States for everyday temperature references. When converting between the two, remember the key reference points: 0°C = 32°F (freezing), 100°C = 212°F (boiling), and 37°C = 98.6°F (body temperature).
