To convert Celsius to Fahrenheit, use this temperature conversion formula:
Steps:
Quick examples:
Tip: The +32 shift matters because Celsius and Fahrenheit start at different zero points.
Use this formula: F = (C × 9/5) + 32.
Multiply the Celsius value by 9, divide by 5, then add 32.
Use this formula: C = (F − 32) × 5/9.
Subtract 32 from the Fahrenheit value, then multiply by 5 and divide by 9.
Fahrenheit sets the freezing point of water at 32°F.
Celsius sets it at 0°C. The +32 shifts the scale to match that offset.
Here are quick reference points:
0°C equals 32°F.
This is the freezing point of water at sea level.
100°C equals 212°F.
This is the boiling point of water at sea level.
Normal body temperature is about 37°C, which equals 98.6°F.
Small changes can be normal based on time of day and the person.
−40° is the same in both scales.
So, −40°C = −40°F.
A simple estimate works for many everyday temps:
Example: 20°C
Double it (40), add 30, you get about 70°F (exact is 68°F).
Yes. The same formula works for any Celsius value, including below zero:
F = (C × 9/5) + 32.
Example: −10°C
(−10 × 9/5) + 32 = −18 + 32 = 14°F.
Most countries use Celsius because it fits the metric system.
The United States and a few others still use Fahrenheit for daily weather and home use.
Both work well, but they feel different:
Use the same formula: F = (C × 9/5) + 32.
For oven temps, many people use quick matches:
Both measure temperature, but the scale size differs.
