In converting the temperature from Celsius to Fahrenheit the formula is F = (9/5)C + 32.
Steps of converting from Celsius (°C) to Fahrenheit (°F)
Step I
Multiply the number of degree by 9.
Step II
Divide the product by 5.
Step III
Add 32 to the result
1. Convert 40 °C to the Fahrenheit scale.
Solution:
Step I: Multiply the number of degree by 9.
= 40° × 9
= 360°
Step II: Divide the product by 5.
= 360° ÷ 5
= 72°
Step III: Add 32 to the result.
= 72 + 32
= 104° F
Therefore, 40° C = 104° F
2. Convert 30°C to the Fahrenheit scale.
Solution:
Step I: Multiply the number of degree by 9.
= 30° × 9
= 270°
Step II: Divide the product by 5.
= 270° ÷ 5
= 54°
Step III: Add 32 to the result.
= 54 + 32
= 86° F
Therefore, 30° C = 86° F
3. Convert 75°C to the Fahrenheit scale.
Solution:
Step I: Multiply the number of degree by 9.
= 75° × 9
= 675°
Step II: Divide the product by 5.
= 675° ÷ 5
= 135°
Step III: Add 32 to the result.
= 135 + 32
= 167° F
Therefore, 75° C = 167° F
4. Convert 20°C to the Fahrenheit scale.
Solution:
Step I: Multiply the number of degree by 9.
= 20° × 9
= 180°
Step II: Divide the product by 5.
= 180° ÷ 5
= 36°
Step III: Add 32 to the result.
= 36 + 32
= 68° F
Therefore, 20° C = 68° F
