Temperature is a fundamental aspect of our daily lives, and its measurement plays a crucial role in various fields, including science, medicine, and weather forecasting. While the Fahrenheit scale is widely used in the United States, the centigrade scale, also known as the Celsius scale, is the preferred temperature measurement system in most countries around the world. In this article, we will delve into the history of the centigrade scale, its advantages, and explore the countries that use it.
A Brief History of the Centigrade Scale
The centigrade scale was invented by Swedish astronomer Anders Celsius in 1742. Celsius, who was also a physicist and mathematician, proposed a temperature scale that was based on the freezing and boiling points of water. He defined the scale such that 0 degrees represented the freezing point of water, and 100 degrees represented the boiling point. This scale was initially called the “centigrade” scale, but it was later renamed to the Celsius scale in honor of its inventor.
Advantages of the Centigrade Scale
The centigrade scale has several advantages over the Fahrenheit scale. One of the main advantages is that it is more intuitive and easier to understand. The scale is based on the decimal system, which makes it easier to perform calculations and conversions. Additionally, the centigrade scale is more precise, with smaller increments between degrees, making it ideal for scientific and medical applications.
International Adoption
The centigrade scale was widely adopted by the international scientific community in the mid-20th century. In 1948, the International Committee for Weights and Measures (ICWM) officially defined the Celsius scale as the standard temperature scale for scientific and technical applications. Today, the centigrade scale is used in almost every country around the world, with the exception of the United States, which still uses the Fahrenheit scale.
Countries That Use Centigrade
The centigrade scale is widely used in most countries around the world. Here are some examples of countries that use the centigrade scale:
- Argentina: Argentina uses the centigrade scale for all temperature measurements, including weather forecasts and scientific applications.
- Australia: Australia adopted the centigrade scale in the 1970s and has since become the standard temperature measurement system in the country.
In addition to these countries, the centigrade scale is also widely used in Europe, Asia, Africa, and South America. In fact, the only countries that still use the Fahrenheit scale are the United States, the Bahamas, Belize, and the Cayman Islands.
Temperature Measurement in Everyday Life
The centigrade scale is used in various aspects of everyday life, including:
Weather Forecasts
Weather forecasts around the world use the centigrade scale to report temperature readings. This allows people to easily understand and compare temperature readings from different regions.
Cooking and Food Preparation
The centigrade scale is widely used in cooking and food preparation. Recipes often specify temperature readings in centigrade, making it easier for cooks to achieve the desired temperature.
Medical Applications
The centigrade scale is used in medical applications, such as measuring body temperature and monitoring temperature readings in hospitals.
Challenges of Using Multiple Temperature Scales
While the centigrade scale is widely used around the world, there are still some challenges associated with using multiple temperature scales. One of the main challenges is conversion between scales, which can be confusing and lead to errors.
Conversion Between Scales
Converting between the centigrade and Fahrenheit scales can be challenging, especially for those who are not familiar with the conversion formulas. The conversion formula from centigrade to Fahrenheit is:
°F = (°C × 9/5) + 32
This formula can be confusing, especially for those who are not mathematically inclined.
Practical Applications of Conversion
Conversion between scales is often necessary in practical applications, such as:
Travel
Travelers often need to convert between temperature scales when traveling to countries that use different scales. For example, a traveler from the United States may need to convert Fahrenheit readings to centigrade when traveling to Europe.
Science and Research
Scientists and researchers often need to convert between temperature scales when working with data from different countries or regions.
Conclusion
In conclusion, the centigrade scale is widely used around the world, with the exception of a few countries that still use the Fahrenheit scale. The centigrade scale has several advantages, including its intuitive and decimal-based system, making it ideal for scientific and medical applications. While there are some challenges associated with using multiple temperature scales, conversion between scales is possible with the use of conversion formulas. As the world becomes increasingly globalized, it is likely that the centigrade scale will become the standard temperature measurement system worldwide.

What is the difference between Centigrade and Celsius?
The terms Centigrade and Celsius are often used interchangeably, but they have a subtle difference. Centigrade is an older term that was used to describe the temperature scale before it was renamed to Celsius in 1948. The name change was made to honor the Swedish astronomer Anders Celsius, who developed the scale in the 18th century.
In modern times, the term Celsius is more commonly used in scientific and everyday applications. However, some countries and cultures still use the term Centigrade, especially in informal contexts. Despite the difference in names, the temperature scale itself remains the same, with 0 degrees being the freezing point of water and 100 degrees being the boiling point.
Which countries use Centigrade or Celsius as their primary temperature scale?
Most countries around the world use Celsius as their primary temperature scale. This includes countries in Europe, Asia, Africa, and South America. In fact, the Celsius scale is used in almost every country except for the United States, which still uses the Fahrenheit scale.
Some countries that use Celsius as their primary temperature scale include Australia, Canada, China, India, Japan, and the United Kingdom. These countries use Celsius in everyday applications, such as weather forecasts, cooking, and scientific research. The widespread use of Celsius is due to its simplicity and ease of use, as well as its adoption as the standard temperature scale in most scientific and international applications.
Why do some countries still use Fahrenheit?
The United States is one of the few countries that still uses Fahrenheit as its primary temperature scale. This is largely due to historical and cultural reasons, as the Fahrenheit scale was widely used in the United States before the Celsius scale was adopted internationally.
Despite the widespread use of Celsius in most countries, the United States has been slow to adopt the new scale. This is partly due to the fact that many everyday applications, such as weather forecasts and cooking, had already standardized on the Fahrenheit scale. Additionally, there has been a lack of government initiative to switch to Celsius, which has contributed to the continued use of Fahrenheit in the United States.
Is Centigrade or Celsius used in scientific research?
In scientific research, Celsius is the preferred temperature scale. This is because Celsius is the standard temperature scale used in most scientific applications, including physics, chemistry, and biology. The use of Celsius in scientific research allows for easy comparison and communication of results across different countries and disciplines.
The use of Celsius in scientific research is also due to its simplicity and ease of use. The Celsius scale is a linear scale, which makes it easy to perform calculations and conversions. Additionally, the Celsius scale is well-suited for most scientific applications, as it is based on the freezing and boiling points of water, which are easily reproducible and measurable.
Can I still use Centigrade in everyday applications?
While Celsius is the preferred temperature scale in most countries, it is still acceptable to use Centigrade in everyday applications. In fact, many people still use the term Centigrade in informal contexts, such as in conversation or in writing.
However, it’s worth noting that using Centigrade in formal or technical applications, such as in science or engineering, may cause confusion. In these contexts, it’s generally better to use the term Celsius, as it is the standard temperature scale used in most scientific and international applications.
How do I convert between Centigrade and Fahrenheit?
Converting between Centigrade (or Celsius) and Fahrenheit is a simple process. To convert from Celsius to Fahrenheit, you can use the following formula: Fahrenheit = (Celsius x 9/5) + 32. To convert from Fahrenheit to Celsius, you can use the following formula: Celsius = (Fahrenheit – 32) x 5/9.
These formulas can be used to convert between Celsius and Fahrenheit in most everyday applications. However, it’s worth noting that there are also many online conversion tools and calculators available that can make the process even easier.
Will the use of Centigrade eventually disappear?
It’s likely that the use of Centigrade will eventually disappear, as Celsius becomes the standard temperature scale used in most countries. In fact, the use of Centigrade has already declined significantly in recent years, as more countries adopt Celsius as their primary temperature scale.
However, it’s worth noting that the use of Centigrade may still persist in some informal contexts, such as in conversation or in writing. Additionally, some countries or cultures may continue to use Centigrade due to historical or cultural reasons. Nevertheless, the trend towards using Celsius as the standard temperature scale is clear, and it’s likely that Centigrade will eventually become a relic of the past.
