How to Convert Fahrenheit to Celsius

Subtract 32, then multiply by 5/9.

The Fahrenheit scale sets water freezing at 32°F and boiling at 212°F. Celsius uses 0°C and 100°C. The formula (°F - 32) × 5/9 converts between them.

When You Need This Conversion

Needed when reading a US weather forecast in Fahrenheit and wanting to gauge the temperature in Celsius, understanding US oven temperatures in cooking recipes, or interpreting a US fever reading from an older thermometer.

Quick Conversion Tip

Subtract 30, then divide by 2 for a fast estimate. For 80°F: (80 - 30) / 2 = 25°C (actual: 26.7°C). Close enough for weather planning.

Common Fahrenheit to Celsius Conversions

  • Water freezes (0°C):32 °F = 0 °C
  • Comfortable room temperature:72 °F = 22.22 °C
  • Normal human body temperature:98.6 °F = 37 °C
  • Water boils at sea level (100°C):212 °F = 100 °C
  • Typical baking temperature:350 °F = 176.67 °C
