What is 45°F in Celsius? Temperature Conversion Explained
Temperature is a fundamental physical quantity that expresses hot and cold. Two of the most commonly used scales for measuring temperature are Fahrenheit (°F) and Celsius (°C). While many countries use Celsius as their primary scale, the Fahrenheit scale is still widely used in the United States and a few other places. This often necessitates converting between the two scales.
Let’s break down how to convert 45°F to Celsius.
The Conversion Formula
The standard formula for converting Fahrenheit to Celsius is:
C = (F – 32) × 5/9
Where:
* C is the temperature in Celsius
* F is the temperature in Fahrenheit
Step-by-Step Conversion of 45°F to Celsius
Now, let’s apply this formula to convert 45°F:
-
Subtract 32 from the Fahrenheit temperature:
The first step in the conversion is to account for the difference in the freezing points of the two scales. Water freezes at 0°C but at 32°F.
45 – 32 = 13 -
Multiply the result by 5/9:
Next, we adjust for the different size of the degree units. A change of 1°C is equivalent to a change of 1.8°F (since 9/5 = 1.8). Therefore, to convert Fahrenheit degrees to Celsius degrees, we multiply by the inverse ratio, 5/9.
13 × (5/9) = 13 × 0.5555… -
Perform the multiplication:
13 × 0.5555… ≈ 7.22
So, 45°F is approximately 7.22°C.
Understanding the Scales
- Fahrenheit Scale: On the Fahrenheit scale, water freezes at 32°F and boils at 212°F (at standard atmospheric pressure). The difference between these two points is 180 degrees.
- Celsius Scale: On the Celsius scale, water freezes at 0°C and boils at 100°C (at standard atmospheric pressure). The difference between these two points is 100 degrees.
This difference in the number of degrees between the freezing and boiling points of water (180 for Fahrenheit, 100 for Celsius) is why the 5/9 (or 9/5 for Celsius to Fahrenheit) factor is crucial in the conversion formula.
Knowing how to convert between Fahrenheit and Celsius is a useful skill, whether you’re traveling, following international weather reports, or working with scientific data.
