Converting temperature from Fahrenheit to Celsius is a fundamental concept in physics and everyday applications. To convert 42 degrees Fahrenheit to Celsius, we use the formula: °C = (°F - 32) × 5/9. Applying this formula, we get: °C = (42 - 32) × 5/9 = 10 × 5/9 = 50/9 = 5.56°C. Therefore, 42°F is equivalent to 5.56°C.
Understanding the Fahrenheit and Celsius Scales
The Fahrenheit scale and the Celsius scale are two different temperature scales used to measure temperature. The Fahrenheit scale was introduced by Gabriel Fahrenheit in 1724, while the Celsius scale was introduced by Anders Celsius in 1742. The main difference between the two scales is the point at which water freezes and boils. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F, while on the Celsius scale, water freezes at 0°C and boils at 100°C.
Conversion Formula and Calculation
The conversion formula from Fahrenheit to Celsius is: °C = (°F - 32) × 5⁄9. This formula is derived from the fact that the Celsius scale is based on the freezing and boiling points of water, which are 0°C and 100°C, respectively. To convert 42°F to Celsius, we plug in the value into the formula: °C = (42 - 32) × 5⁄9 = 10 × 5⁄9 = 50⁄9 = 5.56°C.
| Temperature (°F) | Temperature (°C) |
|---|---|
| 32 | 0 |
| 212 | 100 |
| 42 | 5.56 |
