The conversion of temperature from Celsius to Fahrenheit is a fundamental concept in the field of physics and chemistry. To convert 4 degrees Celsius to Fahrenheit, we use the formula: °F = (°C × 9/5) + 32. Applying this formula, we get: °F = (4 × 9/5) + 32 = 7.2 + 32 = 39.2. Therefore, 4 degrees Celsius is equivalent to 39.2 degrees Fahrenheit.
Understanding the Celsius and Fahrenheit Scales
The Celsius scale, also known as the centigrade scale, is a temperature scale that is based on the freezing and boiling points of water. In this scale, the freezing point of water is defined as 0 degrees Celsius, and the boiling point is defined as 100 degrees Celsius. On the other hand, the Fahrenheit scale is a temperature scale that is based on the freezing and boiling points of water, with the freezing point defined as 32 degrees Fahrenheit and the boiling point defined as 212 degrees Fahrenheit.
Conversion Formula and Calculation
The conversion formula from Celsius to Fahrenheit is: °F = (°C × 9⁄5) + 32. This formula can be applied to any temperature in Celsius to obtain the equivalent temperature in Fahrenheit. For example, to convert 4 degrees Celsius to Fahrenheit, we multiply 4 by 9⁄5, which gives us 7.2, and then add 32 to get 39.2 degrees Fahrenheit.
| Temperature in Celsius | Temperature in Fahrenheit |
|---|---|
| 0°C | 32°F |
| 4°C | 39.2°F |
| 100°C | 212°F |
