In Brazil, Canada, the United Kingdom and in several European countries, the temperature is measured in degrees Celsius (°C). In the United States, Belize, Bahamas, Cayman Islands and Palau, it is measured in degrees Fahrenheit (°F). Fortunately, converting between these two units of measure is fairly easy. Just replace the temperature value with a formula.
Method 1 of 2: Converting Celsius to Fahrenheit
Step 1. The equation is °F = (°C x 1, 8) + 32
You can also use the formula °F = °C x 9 ÷ 5 + 32, which gives the same value because 9 ÷ 5 = 1. 8. Substitute the temperature in Celsius in the equation to convert this value to Fahrenheit.
Step 2. Multiply the temperature in Celsius by 1. 8
Start by finding the temperature in Celsius and multiply it by 1.8.
- For example, if the temperature is 20 degrees Celsius, multiply 20 by 1, 8 to get 36.
- You can also multiply the temperature (20) by 9, resulting in 180, and then divide the result by 5, resulting in 36.
Step 3. Add 32 to the product
After multiplying the temperature by 1, 8 (or by 9 and then dividing by 5), add 32 to the result.
In this case, add 32 to 36 to get 68. So 20°C equals 68°F
Method 2 of 2: Converting Fahrenheit to Celsius
Step 1. The equation is °C = (°F - 32) ÷ 1, 8
You can also use the equation °C = (°F - 32) x 5 ÷ 9 to get the same result. Simply substitute the temperature in Fahrenheit in the formula to get its equivalent in Celsius.
Step 2. Subtract 32 from the temperature in Fahrenheit
The first step is to subtract 32 from the temperature value in Fahrenheit.
For example, if the temperature is 90 degrees Fahrenheit, subtract 32 to get 58
Step 3. Divide the answer by 1, 8
After subtracting 32 from the initial value, the next step is to divide the result by 1, 8.
- For example, divide 58 by 1.8 to get 32.22. So 90°F is equal to 32.22°C.
- You can also multiply 58 by 5, for 290, and then divide the result by 9, for 32, 22. Anyway, 90°F equals 32.22°C.
