Las Fórmulas

°F = (°C × 9/5) + 32. °C = (°F - 32) × 5/9. Truco mental rápido para C→F: duplica y suma 30. 20°C: 20×2+30 = 70°F (real: 68°F — suficientemente cerca). Para F→C: resta 30 y divide entre 2. 80°F: (80-30)/2 = 25°C (real: 26.7°C). El punto donde ambas escalas coinciden: -40° = -40° tanto en Celsius como en Fahrenheit.

Temperaturas de Referencia

Congelación del agua: 0°C = 32°F. Temperatura corporal: 37°C = 98.6°F. Día caluroso: 35°C = 95°F. Día frío: 0°C = 32°F. Horno moderado: 180°C = 350°F. Horno alto: 220°C = 425°F. Fiebre: 38°C = 100.4°F. La mayoría del mundo usa Celsius. Solo EE.UU., Bahamas, Palau, Islas Caimán y Liberia usan Fahrenheit en la vida diaria.
