Fahrenheit to Celsius Converter (°F to °C)

Fahrenheit

The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724 and sets the freezing point of water at 32 °F and the boiling point at 212 °F, creating a 180-degree interval exactly 9/5 of the Celsius interval. Today the Fahrenheit scale is the official temperature scale of the United States and several Caribbean nations.

Celsius

The Celsius scale sets 0 °C at the freezing point of water and 100 °C at its boiling point at standard atmospheric pressure. Proposed by Anders Celsius in 1742, it became the international standard for scientific and everyday temperature measurement in all countries that have adopted SI. The Celsius degree is identical in magnitude to the Kelvin, so temperature differences in Celsius and Kelvin are numerically equivalent, though their zeros differ by exactly 273.15.

Frequently Asked Questions (FAQ)

What is the formula to convert Fahrenheit to Celsius?

The exact formula is °C = (°F − 32) × 5/9. For example: 98.6°F = (98.6 − 32) × 5/9 = 66.6 × 5/9 = 37°C. Water freezes at 32°F = 0°C.

What is 72 degrees Fahrenheit in Celsius?

72°F equals approximately 22.2°C. Using the formula: (72 − 32) × 5/9 = 40 × 5/9 ≈ 22.2°C. This is a typical comfortable room temperature.

What are common Fahrenheit temperatures and their Celsius equivalents?

Key everyday references: 32°F = 0°C (freezing), 50°F = 10°C (cold day), 68°F = 20°C (comfortable indoors), 86°F = 30°C (hot summer day), 98.6°F = 37°C (normal body temperature), 100°F = 37.8°C (mild fever), 104°F = 40°C (high fever — seek medical attention). For cooking: 350°F = 177°C (standard baking), 400°F = 204°C (hot oven), 450°F = 232°C (very hot oven).

Why does the United States still use Fahrenheit when almost every other country uses Celsius?

The US adopted the Fahrenheit scale in the 18th century and attempted a switch to metric (including Celsius) with the Metric Conversion Act of 1975, but the change was voluntary and stalled. Changing thermostats, ovens, weather broadcasts, building codes, and decades of cultural intuition — people who "know" that 70°F is comfortable — proved politically and economically impractical. Today the United States, Liberia, and the Cayman Islands are the only places that officially use Fahrenheit for everyday temperature.
