Celsius
Definition
Celsius (°C) is a widely recognized temperature scale used in scientific, industrial, and everyday contexts worldwide. It is part of the metric system and is based on the freezing and boiling points of water, with water freezing at 0°C and boiling at 100°C under standard atmospheric pressure. The unit is denoted by the symbol °C.
History/Origin
The Celsius scale was introduced in 1742 by Swedish astronomer Anders Celsius. Initially, the scale was inverted, with 0°C as the boiling point and 100°C as the freezing point of water. It was later standardized to the current format. Its integration into the metric system made Celsius the preferred choice for temperature measurement in most countries and scientific disciplines.
Current Use
Celsius is the standard temperature scale in nearly all countries except the United States and a few others that use Fahrenheit. It is integral to scientific research, weather reporting, cooking, and medical applications. Its straightforward 100-point scale makes it ideal for practical and scientific purposes alike.
Fahrenheit
Definition
Fahrenheit (°F) is a temperature scale predominantly used in the United States and its territories. It is part of the Imperial measurement system. On this scale, water freezes at 32°F and boils at 212°F under standard atmospheric pressure. The unit is denoted by the symbol °F.
History/Origin
The Fahrenheit scale was developed in 1724 by physicist Daniel Gabriel Fahrenheit. He defined the scale based on three key points: the freezing point of a brine solution (0°F), the freezing point of pure water (32°F), and the approximate average human body temperature (originally 96°F, later corrected to 98.6°F). The scale was widely used in English-speaking countries before being largely replaced by Celsius in most of the world.
Current Use
Fahrenheit remains the primary temperature scale used in the United States for weather forecasts, cooking, and industrial processes. While Celsius and Kelvin dominate scientific applications, Fahrenheit is culturally and practically entrenched in the United States and a few other regions.
Conversion Details
Conversion Formula and Factor
To convert Celsius (°C) to Fahrenheit (°F), use the following formula:
[ \text{°F} = \left(\text{°C} \times \frac{9}{5}\right) + 32 ]
This formula reflects the relationship between the two scales.
Quick Reference Conversion Table
Step-by-Step Conversion Instructions
Example: Convert 25°C to Fahrenheit
Start with the formula: [ \text{°F} = \left(\text{°C} \times \frac{9}{5}\right) + 32 ]
Multiply the Celsius value by 9/5: [ 25 \times \frac{9}{5} = 45 ]
Add 32 to the result: [ 45 + 32 = 77 ]
Result: 25°C equals 77°F.
Practical Examples
Example 1: Freezing Point of Water
Celsius: 0°C
Conversion: [ \text{°F} = \left(0 \times \frac{9}{5}\right) + 32 = 32°F ]
Result: 0°C equals 32°F, the freezing point of water.
Example 2: Human Body Temperature
Celsius: 37°C
Conversion: [ \text{°F} = \left(37 \times \frac{9}{5}\right) + 32 ] [ \text{°F} = 66.6 + 32 = 98.6°F ]
Result: 37°C equals 98.6°F, the average human body temperature.
