To convert Celsius to Fahrenheit, multiply by 9/5 (1.8) and add 32.
Formula: °F = (°C × 9/5) + 32
A quick mental shortcut: double the Celsius value and add 30 — this gives an approximation within 2–3°F.
- 0°C = 32°F (freezing point of water)
- 20°C = 68°F (comfortable room temperature)
- 37°C = 98.6°F (normal body temperature)
- 100°C = 212°F (boiling point of water at sea level)
The United States uses Fahrenheit for everyday temperatures — weather forecasts, oven temperatures, and body temperature readings. International travelers visiting the US need to convert Celsius weather forecasts. US recipes call for Fahrenheit oven temperatures (350°F = 177°C is a typical baking temperature). Meat thermometers in the US read Fahrenheit.
The US is one of only five countries still using Fahrenheit for everyday purposes (alongside the Bahamas, Belize, Cayman Islands, and Palau). Water freezes at 32°F and boils at 212°F. A "comfortable" US summer day is around 75–85°F (24–29°C). US weather apps and thermostats default to Fahrenheit.
