About both units

From

Celsius

°C

The Celsius scale defines 0 °C as the freezing point of water and 100 °C as the boiling point at standard atmospheric pressure. Proposed by Anders Celsius in 1742, it is the everyday temperature unit in all countries except the US, Belize, the Bahamas, the Cayman Islands and Liberia.

Real-world: Room temperature is about 20 °C. Normal body temperature is 37 °C. Typical fridge setting is 4 °C. European winter can reach −20 °C; desert summer 45+ °C.

Fahrenheit

°F

The Fahrenheit scale places water's freezing point at 32 °F and its boiling point at 212 °F. Proposed by Daniel Gabriel Fahrenheit in 1724, it is still the official temperature unit in the US, Belize and a few Caribbean countries. Normal human body temperature is 98.6 °F.

Real-world: US room temperature 68–72 °F. Body temperature 98.6 °F. Fever 100.4 °F. Pizza oven 450 °F.

Tips & common mistakes

Quick tips

0 °C = freezing; 100 °C = boiling. Easy anchor points.
Mental F conversion: double the °C and add 30 (rough). 20 °C → 70 °F (actual 68).
Medical thermometers show 0.1 °C resolution — a rise from 37.0 to 37.5 matters.

Avoid these

Using "degrees centigrade" — the scale was renamed Celsius in 1948.
Assuming a linear relationship between °C and °F without the +32 offset.
Interpreting UK winter forecasts in °F by habit — UK uses °C.

Frequently asked questions

How many degrees Fahrenheit in a celsius?

One celsius equals 33.8 degrees Fahrenheit.

How do I convert degrees Celsius to degrees Fahrenheit?

Temperature conversion is non-linear. From Celsius to Fahrenheit use the specific formula — this tool applies it automatically.

What is 100 degrees Celsius in degrees Fahrenheit?

100 degrees Celsius equals 212 degrees Fahrenheit.

Is a celsius bigger than a fahrenheit?

Temperature units compare by scale, not by size of one degree. Celsius and Fahrenheit use different zero points.

How to convert degrees Celsius to degrees Fahrenheit without a calculator?

Use the mental shortcut relevant to these temperature scales — but for accuracy always verify with a calculator.
