Converting the Temperature from Fahrenheit to Celsius

In converting the temperature from Fahrenheit to Celsius the formula is, C = (5/9)(F – 32);

Converting the Temperature from Fahrenheit to Celsius

The steps of converting from Fahrenheit to Celsius are reversed here.

Step ISubtract 32 from the degrees.

Step II: Multiply the result by 5. 

Step III: Divide the product by 9.

For Example:

1. Convert 86°F to the Celsius scale.

Solution:

Step I:

Subtract 32 from the degrees.

= 86° - 32

= 54°

Step II:

Multiply the result by 5.

= 54° × 5

= 270°

Step III:

Divide the product by 9.

= 270° ÷ 9

= 30° C

Therefore, 86° F = 30° C



2. Convert 104° F to the Celsius scale.

Solution:

Step I:

Subtract 32 from the degrees.

= 104° - 32

= 72°

Step II:

Multiply the result by 5.

= 72° × 5

= 360°

Step III:

Divide the product by 9.

= 360° ÷ 9

= 40° C

Therefore, 104° F = 40° C



3. Convert 113°F to the Celsius scale.

Solution:

Step I:

Subtract 32 from the degrees.

= 113° - 32

= 81°

Step II:

Multiply the result by 5.

= 81° × 5

= 405°

Step III:

Divide the product by 9.

= 405° ÷ 9

= 45° C

Therefore, 113° F = 45° C



4. Convert 122°F to the Celsius scale.

Solution:

Step I:

Subtract 32 from the degrees.

= 122° - 32

= 90°

Step II:

Multiply the result by 5.

= 90° × 5

= 450°

Step III:

Divide the product by 9.

= 450° ÷ 9

= 50° C

Therefore, 122° F = 50° C


5. Convert the following Fahrenheit into Celsius scale.

(i) 95° F

(ii) 131° F


Solution:

(i) 95° F

We know that C = (F - 32) × 59

95° F = (95 - 32) × 59

         = 63 × 59

         = 3159

         = 35° C

Hence, 95° F = 35° C


(ii) 131° F

We know that C = (F - 32) × 59

131° F = (131 - 32) × 59

         = 99 × 59

         = 4959

         = 55° C

Hence, 131° F = 55° C
