Converting Fahrenheit to Celsius
Step 1: Write Down the Formula
Celsius (°C) = 5/9 × (Fahrenheit (°F) – 32)
Step 2: Substitute the Given Fahrenheit Temperature into the Formula
Given Fahrenheit temperature is 45°F.
Celsius (°C) = 5/9 × (45 – 32)
Step 3: Perform the Subtraction Inside the Parentheses
45 – 32 = 13
So the formula now becomes:
Celsius (°C) = 5/9 × 13
Step 4: Multiply the Result by 5/9
Celsius (°C) = 5/9 × 13
Celsius (°C) = 65/9
Step 5: Simplify the Fraction
65/9 = 7.22
Final Answer
45 degrees Fahrenheit is 7.22 degrees Celsius.
Examples of Fahrenheit to Celsius Conversions
Convert 5°F to °C
Celsius (°C) = 5/9 × (5 – 32)
Celsius (°C) = 5/9 × (-27)
Celsius (°C) = -135/9
Celsius (°C) = -15
Convert 250°F to °C
Celsius (°C) = 5/9 × (250 – 32)
Celsius (°C) = 5/9 × 218
Celsius (°C) = 1090/9
Celsius (°C) ≈ 121.11
Convert 40°F to °C
Celsius (°C) = 5/9 × (40 – 32)
Celsius (°C) = 5/9 × 8
Celsius (°C) = 40/9
Celsius (°C) ≈ 4.44
Convert 20°F to °C
Celsius (°C) = 5/9 × (20 – 32)
Celsius (°C) = 5/9 × (-12)
Celsius (°C) = -60/9
Celsius (°C) ≈ -6.67
