Fahrenheit (°F)
Temperature
°F = °C × 9/5 + 32 exactly; the conversion is affine, not a single multiplying factor.

How to Convert Fahrenheit to Celsius
This conversion uses an offset formula, so it cannot be described by a single multiplication factor.
Fórmula: °C = (°F - 32) × 5/9
Inversa: °F = (°C × 9/5) + 32
Exemplo Passo a Passo
- Start with your value in Fahrenheit. For example: 5 °F
- Apply °C = (°F - 32) × 5/9
- The result is: -15 °C
Sobre Fahrenheit
The Fahrenheit scale sets 32°F as the freezing point and 212°F as the boiling point of water. It is primarily used in the United States.
Curiosidade: Daniel Fahrenheit chose 96°F as his upper reference point, based on human body temperature (which he measured slightly inaccurately).
Usos comuns: weather (US), cooking (US), HVAC.
Sobre Celsius
The Celsius scale sets 0°C as the freezing point and 100°C as the boiling point of water at standard pressure. It is used by most countries worldwide.
Curiosidade: Anders Celsius originally proposed a scale where 100° was freezing and 0° was boiling—it was later reversed!
Usos comuns: weather, cooking, science.
