How to convert fahrenheit to celsius
Fahrenheit (°F) and Celsius (°C) both measure temperature. Whether you are studying, traveling, cooking, or working on a project, converting between them should be fast and accurate.
Looking for the opposite direction? See our dedicated celsius to fahrenheit converter — same formula reversed, with content written for that direction.
The standard relationship used on this page means that 1 fahrenheit equals -17.222222 °C. Enter any number in the calculator — use the swap button to reverse the direction without leaving the page.
68°F is 20°C — handy for oven settings when following a European recipe or science worksheet.

When you'll use this
- Converting a US recipe's oven temperature (°F) for someone cooking with a Celsius-only oven abroad
- Understanding a US weather forecast in °F for an international visitor or new immigrant used to Celsius
- Setting a US-made thermostat correctly for a tenant or guest who thinks in Celsius
- Completing a science or engineering assignment that requires Celsius input from a Fahrenheit source measurement
- Converting a US grill or smoker temperature setting (°F) for a metric-calibrated thermometer
Practical note
This page is essential for anyone cooking American recipes outside the US: a classic "350°F" baking instruction converts to about 177°C, the number that actually needs to go into a European or Australian oven dial. It also helps with everyday communication — a US weather report of "95°F" (a genuinely hot day) converts to about 35°C, giving an international reader or recent immigrant an immediate, intuitive sense of the heat without needing to mentally recalibrate an unfamiliar temperature scale from scratch.
Tips
- A fast estimate: subtract 30 from the Fahrenheit figure and halve it — rough, but close enough for a quick weather check.
- US oven recipes commonly use 350°F, 375°F, and 400°F — these convert to about 177°C, 191°C, and 204°C, worth memorizing if you frequently cook American recipes on a Celsius oven.
- Double-check which "100" you mean: 100°F (about 37.8°C) is a hot summer day, while 100°C is boiling water — a mix-up that has real consequences when following a recipe.
