Understanding the Conversion between Centigrade and Fahrenheit
Centigrade and Fahrenheit are two different scales used to measure temperature. Centigrade, also known as Celsius, is the metric unit of temperature, while Fahrenheit is commonly used in the United States and a few other countries. To convert between the two scales, you’ll need to understand the following relationships:
- Freezing point of water: 0°C (centigrade) / 32°F (Fahrenheit)
- Boiling point of water: 100°C (centigrade) / 212°F (Fahrenheit)
The difference between the freezing and boiling points of water is 100° in both scales, but the size of each degree is different. One degree Centigrade is equivalent to 1.8 degrees Fahrenheit. This means that a temperature change of 10°C is equal to a change of 18°F.
To convert from Celsius to Fahrenheit, you can use the following formula:
“`
°F = (°C x 1.8) + 32
“`
For example, to convert 20°C to Fahrenheit:
“`
°F = (20°C x 1.8) + 32
°F = 36°F + 32
°F = 68°F
“`
To convert from Fahrenheit to Celsius, you can use the following formula:
“`
°C = (°F – 32) / 1.8
“`
For example, to convert 77°F to Celsius:
“`
°C = (77°F – 32) / 1.8
°C = 45°F / 1.8
°C = 25°C
“`
