Fahrenheit to Celsius: Definition, History, Uses, and Examples
Definition
Fahrenheit (°F) is a temperature scale primarily used in the United States, where 32° is the freezing point and 212° is the boiling point of water at 1 atm. Celsius (°C) is a metric scale with 0° and 100° as freezing and boiling points respectively. Conversion is linear: °C = (°F − 32) × 5/9.
Origin or History
The Fahrenheit scale was introduced by Daniel Gabriel Fahrenheit in the early 18th century. The Celsius scale, proposed by Anders Celsius in 1742, later adopted the modern orientation (0° freezing, 100° boiling).
Current Use
- Weather: US weather reports use °F; international contexts often use °C.
- Cooking: Oven settings and recipes in the US typically use °F.
- HVAC: Thermostat settings for homes and offices.
- Science: Conversions between °F and °C when needed for datasets.
