Fahrenheit

Fahrenheit is a temperature scale where water freezes at 32 °F and boils at 212 °F under standard atmospheric pressure.

The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit and remains common for everyday temperature use in the United States.

Fahrenheit is used in US weather forecasts, thermostats, ovens, HVAC settings, body temperature references, and household temperature discussions.

Celsius

Celsius is a temperature scale where water freezes at 0 °C and boils at 100 °C under standard atmospheric pressure.

Celsius developed from centigrade temperature measurement and became the common metric temperature scale worldwide.

Celsius is used in science, medicine, weather reporting outside the United States, cooking, engineering, and everyday metric temperature measurement.

How to Convert Fahrenheit to Celsius

Mathematically, celsius (°C) = fahrenheit (°F) converted with the formula below.

1 °F = -17.222222 °C

1 °C = 33.8 °F

Formula: (value - 32) × 5/9

Example: 25 °F = -3.888889 °C

  1. Start with the temperature value in degrees Fahrenheit.
  2. Subtract 32 to align the Fahrenheit freezing point with Celsius.
  3. Multiply the result by 5/9.
  4. Report the converted result in degrees Celsius.

Precision note: Use Celsius = (Fahrenheit - 32) x 5/9. Round final values based on whether the context is weather, cooking, medical, or scientific.

Common Use Cases for °F to °C

  • Reading US weather forecasts in Celsius.
  • Converting oven, room, or thermostat values into metric units.
  • Preparing travel, classroom, or medical notes for an international audience.
  • Checking Fahrenheit source data against Celsius-based specifications.

FAQ

What is 32 degrees Fahrenheit in Celsius?

32 °F equals 0 °C.

What is 98.6 degrees Fahrenheit in Celsius?

98.6 °F equals 37 °C.

Why subtract 32 first?

Fahrenheit and Celsius have different zero points, so the offset must be removed before scaling by 5/9.
