To convert 105 degrees Fahrenheit (°F) to Celsius (°C), we use the formula: °C = (°F - 32) × 5/9. Applying this formula, we get: °C = (105 - 32) × 5/9 = 73 × 5/9 = 40.5556 °C. Therefore, 105 °F is equivalent to approximately 40.56 °C.
Understanding the Fahrenheit and Celsius Scales
The Fahrenheit scale is a temperature scale that is based on the freezing and boiling points of water, where 32 °F is the freezing point and 212 °F is the boiling point. On the other hand, the Celsius scale is based on the same reference points but with 0 °C as the freezing point and 100 °C as the boiling point. This fundamental difference in reference points is why conversions between the two scales are necessary for accurate temperature representation in different contexts.
Conversion Formula and Calculation
The formula to convert from Fahrenheit to Celsius is °C = (°F - 32) × 5⁄9. This formula is derived from the difference in the zero points and the scale factors of the two temperature scales. By subtracting 32 from the Fahrenheit temperature, we adjust for the zero-point difference, and then multiplying by 5⁄9 adjusts for the scale factor difference between the two scales.
| Temperature in °F | Temperature in °C |
|---|---|
| 32 °F | 0 °C |
| 212 °F | 100 °C |
| 105 °F | 40.56 °C |
