°F to °C formula and worked examples

Formula and Step-by-Step

°C = (°F - 32) × 5/9

Step-by-step: 1 °F to °C

  1. Start with 1°F
  2. Subtract 32: 1 - 32 = -31
  3. Multiply by 5/9: -31 × 0.5556 = -17.22
  4. Result: 1°F = -17.22°C

Conversion Table

Common fahrenheit to celsius values. The table and calculator both use the same conversion formula shown above.

What Does That Feel Like?

  • 32 °F = 0 °C, water freezes
  • 72 °F = 22.2 °C, comfortable room temperature
  • 98.6 °F = 37 °C, normal body temperature
  • 212 °F = 100 °C, water boils
  • 350 °F = 176.7 °C, common baking temperature

Quick Mental Conversion

For a rough estimate, subtract 30 then halve. For example, 72 °F: minus 30 is 42, halved is 21. The exact answer is 22.2 °C.

What Are Fahrenheit and Celsius?

What is a Fahrenheit?

Fahrenheit is a temperature scale where 32 degrees is the freezing point of water and 212 degrees is the boiling point. It is primarily used in the United States.

What is a Celsius?

Celsius is a temperature scale where 0 degrees is the freezing point of water and 100 degrees is the boiling point. It is used by most countries worldwide.

Why convert fahrenheit to celsius?

People typically convert fahrenheit to celsius when understanding US weather forecasts, cooking temperatures, and HVAC settings in metric.

Frequently Asked Questions

1 fahrenheit equals -17.22 celsius. This uses the formula: °C = (°F - 32) × 5/9.
The formula is: °C = (°F - 32) × 5/9. See the °F to °C formula page for step-by-step worked examples.
Use the celsius to fahrenheit converter. 1 °C = 33.8 °F.
Most unit conversions use simple multiplication because the scales share a zero point. Temperature scales have different zero points (0 degrees C = 32 degrees F), so the formulas require both multiplication and addition or subtraction.
For Celsius to Fahrenheit, double the value and add 30. For Fahrenheit to Celsius, subtract 30 and halve. These give close approximations for everyday use.
