What is the formula for converting Fahrenheit to Celsius?

The formula is: °C = (°F - 32) × 5/9. For example, to convert 68°F: (68-32) × 5/9 = 36 × 5/9 = 20°C. Our Fahrenheit to Celsius converter applies this formula automatically for instant results.

At what temperature are Fahrenheit and Celsius equal?

Fahrenheit and Celsius scales intersect at -40 degrees (-40°F = -40°C). This is the only temperature where both scales show the same numerical value.

What are common Fahrenheit to Celsius conversions?

Common temperature conversions include: 32°F = 0°C (water freezing), 68°F = 20°C (room temperature), 98.6°F = 37°C (body temperature), 212°F = 100°C (water boiling), and 451°F = 233°C (paper ignition).

Why does the United States use Fahrenheit instead of Celsius?

The US adopted the Fahrenheit scale before the metric system became internationally standardized. Fahrenheit provides more granular whole numbers for everyday weather temperatures, with 0-100°F covering most climate conditions.

How accurate is this Fahrenheit to Celsius converter?

Our converter uses the exact mathematical formula with high decimal precision, making it suitable for scientific research, cooking, weather analysis, and professional applications. The accuracy meets all international standards.

How do I convert 100 degrees Fahrenheit to Celsius?

100°F converts to 37.78°C using the formula: (100-32) × 5/9 = 68 × 5/9 = 37.78°C. This temperature is close to normal human body temperature.
