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.

## Steps

### 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.
