Celsius Temperature Scale

The Celsius temperature scale, also known as the centigrade scale, is widely used across the globe. Developed by Swedish astronomer Anders Celsius in 1742, it defines:

• 0°C as the freezing point of water
• 100°C as the boiling point of water at standard atmospheric pressure

Scientific and Everyday Significance

Celsius plays a crucial role in scientific research, weather reporting, and everyday life. Its alignment with the metric system and clear reference points make it a preferred choice for various applications, from understanding weather patterns to monitoring body temperature.

Conversions and Calculations

Celsius can be easily converted to other temperature scales:

• Fahrenheit: °F = (°C × 9/5) + 32
• Kelvin: K = °C + 273.15

For instance, 25°C is equivalent to 77°F and 298.15 K.

A Bit of History

Interestingly, the original Celsius scale by Anders Celsius was reversed, with 0°C as the boiling point and 100°C as the freezing point. It was later inverted by Carl Linnaeus, resulting in the scale we use today.
