About the degree Celsius and the degree Fahrenheit
The Celsius scale puts the freezing point of water at 0 degrees and its boiling point at 100 degrees at sea-level pressure. It is used for weather, cooking and science in nearly every country outside the United States.
On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees, so there are 180 degrees between the two. It is the everyday scale for weather, cooking and body temperature in the United States and a few other places.
Zero degrees Celsius is 32 °F, and 100 °C is 212 °F.
Everyday sizes in degrees Celsius and degrees Fahrenheit
| Everyday example (approximate) | In degrees Celsius | In degrees Fahrenheit |

| The coldest air temperature ever recorded | -89.2 °C | -128.56 °F |
| A home freezer | -18 °C | -0.4 °F |
| Water freezes | 0 °C | 32 °F |
| A fridge | 4 °C | 39.2 °F |
| A comfortable room | 21 °C | 69.8 °F |
| A hot summer day | 35 °C | 95 °F |
| Normal human body temperature | 37 °C | 98.6 °F |
| A hot bath | 40 °C | 104 °F |
Degrees celsius to degrees Fahrenheit FAQ
What is 0 °C in °F?
0 °C equals 32 °F. For reference, 100 °C equals 212 °F, and the two scales cross at a different point only for Celsius and Fahrenheit, which agree at -40 degrees.
How do I convert degrees Celsius to degrees Fahrenheit without a calculator?
convert 30 °C to °F. 30 × 9/5 = 54, then add 32 to get 86 °F. Reverse it with °C = (°F − 32) × 5/9. In your head, double the Celsius value and add 30: 20 °C becomes about 70 °F (the exact answer is 68 °F). The shortcut drifts by a few degrees at the extremes.
What is water freezes in degrees Fahrenheit?
Water freezes is about 0 degrees Celsius, which is 32 degrees Fahrenheit. Treat that as an approximate everyday figure rather than an official measurement.
Which scale does my country use, degrees Celsius or degrees Fahrenheit?
Celsius is the everyday scale in almost every country except the United States; 0 °C is 273.15 K. Fahrenheit is used mainly in the United States and a few smaller countries; one Fahrenheit degree is 5/9 of a Celsius degree.
