There are a few formulas that you can use to convert degrees Celsius to degrees Fahrenheit.
°C to °F Conversion Formula
Convert °C to °F using the widely accepted conversion formula:
°F = °C × 9/5 + 32
The temperature in degrees Fahrenheit is equal to the temperature in degrees Celsius times 9/5, plus 32. Insert the °C temperature measurement in the formula and then solve to find the result.
For example, let's convert 50 °C to °F:
50 °C = 50 × 9/5 + 32
50 °C = 90 + 32
50 °C = 122 °F
Alternate Celsius to Fahrenheit Formula
The National Institute of Standards and Technology defines a simplified formula for the conversion:[1]
°F = (°C × 1.8) + 32
This is a reduced version of the more widely accepted formula shown above.
How to Convert a Temperature Without a Calculator
To convert Celsius to Fahrenheit without a calculator, you can use a shortcut method. Multiply the temperature by two, then add 30.
Bear in mind that this is not a precise method; it's a quick shortcut to get a rough conversion when you don't have a calculator handy.
For example, let's use this shortcut to convert 20 °C to Fahrenheit.
Start by multiplying the temperature by 2.
20 °C × 2 = 40
Then, add 30.
40 + 30 = 70
So, 20 °C is approximately 70 °F using this method.
The Fahrenheit and Celsius scales are both used to measure temperature. Read on to learn more about each of them.

What Is Celsius?
The Celsius temperature scale, also commonly referred to as the centigrade scale, is defined in relation to the kelvin. Specifically, degrees Celsius is equal to kelvins minus 273.15.[1]
The degree Celsius is the SI derived unit for temperature in the metric system. A degree Celsius is sometimes also referred to as a degree centigrade. Celsius can be abbreviated as C; for example, 1 degree Celsius can be written as 1 °C.

What Is Fahrenheit?
The Fahrenheit scale is a temperature scale that defines the melting point of water as 32 degrees and the boiling point of water at 212 degrees.[2] There are 180 intervals between 32 °F and 212 °F, each corresponding to one degree.
The degree Fahrenheit is a US customary and imperial unit of temperature. Fahrenheit can be abbreviated as F; for example, 1 degree Fahrenheit can be written as 1 °F.
