Temperature conversion formula
Celsius (°C) → Fahrenheit (°F): °F =°C × 9/5 + 32
Fahrenheit (℉) → Celsius (℃): ℃ = (℉ – 32) × 5/9
Celsius (°C) → Kelvin (K): K =°C + 273.15
Kelvin (K) → Celsius (°C): °C = K – 273.15
Fahrenheit (℉) → Celsius (℃): ℃ = (℉ – 32) × 5/9
Celsius (°C) → Kelvin (K): K =°C + 273.15
Kelvin (K) → Celsius (°C): °C = K – 273.15
Key temperature reference point
Water freezing point: 0℃ = 32℉ = 273.15K
Body temperature (normal): 36.5–37°C = 97.7–98.6°F
Boiling point of water: 100℃ = 212℉ = 373.15K
Absolute Zero: -273.15℃ = -459.67℉ = 0K
Body temperature (normal): 36.5–37°C = 97.7–98.6°F
Boiling point of water: 100℃ = 212℉ = 373.15K
Absolute Zero: -273.15℃ = -459.67℉ = 0K
The United States, Canada, and other countries use Fahrenheit (℉). When traveling, convert the local temperature to Celsius to get a sense of the wind chill.
Frequently Asked Questions
How many degrees in Celsius is 72 degrees Fahrenheit?
(72 – 32) × 5/9 = 22.2℃. A US weather forecast of 72℉ is approximately 22℃, which is pleasant weather.
How many degrees Fahrenheit is 100 degrees Celsius?
100 × 9/5 + 32 = 212℉. This is the boiling point of water.
What is Kelvin (K)?
It is a unit of absolute temperature, with absolute zero (-273.15°C) set as 0. It is used in science and engineering, and 0K is the theoretically lowest possible temperature.
