Weather
The perceived temperature also depends on humidity, wind, sun and activity.
| °C | °F | Reference |
|---|---|---|
| < 0 | < 32 | Below freezing |
| 0 a 10 | 32 a 50 | Cold |
| 15 a 25 | 59 a 77 | Mild |
| ≥ 30 | ≥ 86 | Hot |

Food safety
Minimum internal temperature references published by USDA FSIS.
- Whole cuts of beef and pork: 63 °C / 145 °F, with a 3-minute rest.
- Ground meat: 71 °C / 160 °F.
- Poultry: 74 °C / 165 °F.
Health
Normal body temperature varies by person, age, time of day and measurement method. This converter does not diagnose fever.
A body temperature below 35 °C / 95 °F may indicate hypothermia and requires urgent medical attention.

Formulas principales
Conversions use full precision and are rounded only for display.
Celsius to Fahrenheit
°F = (°C × 9 / 5) + 32
Fahrenheit to Celsius
°C = (°F - 32) × 5 / 9
Celsius to Kelvin
K = °C + 273.15
Kelvin is the SI base unit of thermodynamic temperature and is written without a degree symbol. See the reference from NIST.
Frequently asked questions
How do you convert Celsius to Fahrenheit?
Multiply Celsius by 9/5 and add 32. For example, 20 °C equals 68 °F.
How do you convert Fahrenheit to Celsius?
Subtract 32 from Fahrenheit and multiply by 5/9. For example, 68 °F equals 20 °C.
What is 37 degrees Celsius in Fahrenheit?
37 °C equals 98.6 °F. It is a common body-temperature reference, although normal values vary by person and measurement method.
What is 100 °F in Celsius?
100 °F is approximately 37.78 °C.
What is absolute zero in Celsius?
Absolute zero equals -273.15 °C, 0 K or -459.67 °F. It is the theoretical minimum temperature.
Why does Kelvin not use the degree symbol?
Kelvin is the SI base unit of thermodynamic temperature. Its symbol is K, without a degree sign.
At what temperature are Celsius and Fahrenheit equal?
The two scales meet at -40: -40 °C equals -40 °F.
What is 180 °C in a Fahrenheit oven?
180 °C equals 356 °F.
