Convert the following temperatures to °C 55.6 °F -72.5 °F 465 °F 128 K
The correct Answer and Explanation is:
Let’s start with the conversions:
- 55.6 °F to Celsius: (55.6−32)×59=13.1°C\frac{(55.6 – 32) \times 5}{9} = 13.1 °C
- -72.5 °F to Celsius: (−72.5−32)×59=−58.1°C\frac{(-72.5 – 32) \times 5}{9} = -58.1 °C
- 465 °F to Celsius: (465−32)×59=240.6°C\frac{(465 – 32) \times 5}{9} = 240.6 °C
- 128 K to Celsius: 128−273.15=−145.2°C128 – 273.15 = -145.2 °C
Explanation
Temperature conversion is a fundamental aspect of science, engineering, and daily life. Different temperature scales exist to accommodate various contexts, and Celsius (°C) is widely used in scientific research and daily applications. Fahrenheit (°F) is primarily used in the United States, while Kelvin (K) is used in scientific fields, particularly physics.
The conversion formulas help translate values across these scales:
- Fahrenheit to Celsius The formula:
°C=(°F−32)×59°C = \frac{(°F – 32) \times 5}{9}
This equation accounts for the differences in zero points and unit scaling between Fahrenheit and Celsius. The freezing point of water is 32 °F, which translates to 0 °C, and the boiling point is 212 °F, equivalent to 100 °C.
- Kelvin to Celsius The formula:
°C=K−273.15°C = K – 273.15
Kelvin is an absolute temperature scale where 0 K represents absolute zero—the theoretical lowest possible temperature where molecular motion ceases. To find the Celsius equivalent, we subtract 273.15 from the Kelvin temperature.
The conversions above illustrate how temperature values can vary widely based on the units used. For instance, -145.2 °C from 128 K represents extreme cold, far below freezing temperatures encountered on Earth. On the other hand, 240.6 °C from 465 °F is extremely hot, comparable to industrial furnaces.
Understanding these conversions aids in scientific calculations, engineering applications, and even everyday tasks like interpreting weather reports or adjusting cooking temperatures in different regions.
