Definition

Degrees Celsius (°C) is a unit of measurement for temperature. It is based on the freezing point of water (0°C) and the boiling point of water (100°C). The scale is divided into 100 degrees, with each degree representing a change in temperature of 1°C.

The Celsius scale is used in most countries around the world. However, in the United States, the Fahrenheit scale is still more commonly used.

Here are some examples of how degrees Celsius are used:

  • Weather: The weather forecast is usually given in degrees Celsius.
  • Cooking: Recipes often specify the temperature of the oven or stove in degrees Celsius.
  • Science: Scientists use degrees Celsius to measure temperature in their experiments.

How can the word be used?

The boiling point of water is 100°C.

Different forms of the word

Noun: degree Celsius.

Adjective: Celsius.

Abbreviation: °C.

Symbol: °C.

Etymology

The word "degrees Celsius" is named after the Swedish astronomer Anders Celsius, who developed the scale in 1742. The scale was originally called the centigrade scale, because it was divided into 100 degrees. However, in 1948, the International Bureau of Weights and Measures (BIPM) renamed the scale to the Celsius scale, in honor of Anders Celsius.

AQA Science Exam Question and Answer

Question:

Question: Convert a temperature of 80 degrees Celsius to its equivalent in Fahrenheit. Explain the process of converting temperatures between degrees Celsius and Fahrenheit, including the formula used for the conversion.

Answer:

Temperature Conversion:

To convert a temperature from degrees Celsius (°C) to Fahrenheit (°F), you can use the following formula: °F = (°C × 9/5) + 32.

Temperature Conversion Example:

  • Given the temperature of 80 degrees Celsius, let's convert it to Fahrenheit:

°F = (80 × 9/5) + 32.

°F = 144 + 32.

°F = 176.

Therefore, 80 degrees Celsius is equivalent to 176 degrees Fahrenheit.

In this conversion, you multiply the temperature in Celsius by 9/5 (or 1.8) and then add 32 to get the temperature in Fahrenheit. This conversion is useful for understanding and comparing temperatures between different temperature scales in various situations.
