Celsius

The Celsius scale is a temperature scale used in the metric system for measuring temperature. It is named after the Swedish astronomer Anders Celsius, who developed a similar temperature scale in 1742. On the Celsius scale, the freezing point of water is 0 degrees, and the boiling point of water is 100 degrees, at standard atmospheric pressure.

Converting Celsius to Fahrenheit

To convert a temperature from Celsius to Fahrenheit, you can use the following formula:

Fahrenheit = (Celsius × 9/5) + 32

Converting Celsius to Kelvin

To convert a temperature from Celsius to Kelvin, you can use the following formula:

Kelvin = Celsius + 273.15

Practice Problems

1. Convert 25 degrees Celsius to Fahrenheit.
2. Convert 100 degrees Celsius to Kelvin.

Solutions

1. Convert 25 degrees Celsius to Fahrenheit:

Fahrenheit = (25 × 9/5) + 32

Fahrenheit = 45 + 32

Fahrenheit = 77 degrees

2. Convert 100 degrees Celsius to Kelvin:

Kelvin = 100 + 273.15

Kelvin = 373.15 degrees

Summary

In summary, the Celsius scale is a temperature scale used in the metric system, with the freezing point of water at 0 degrees and the boiling point of water at 100 degrees. It is commonly used in scientific and everyday applications for measuring temperature.
