Celsius to Fahrenheit – How to Convert Celsius (°C) to Fahrenheit (°F)

The Celsius scale largely replaced the Fahrenheit scale in most countries during the mid to late 20th century. Today, nearly all nations use Celsius, except for those that have not adopted the metric system, like the United States.

To convert Celsius (°C) to Fahrenheit (°F), use this formula: Multiply the Celsius temperature by 9/5 (or 1.8) and then add 32.

Celsius History: The Celsius scale was created by Anders Celsius, a Swedish astronomer, in 1742. Originally, his scale had 0°C as the boiling point of water and 100°C as the freezing point, but it was later reversed to its modern form. The Celsius scale became widely used due to its simplicity and compatibility with the metric system.

By the mid to late 20th century, most countries adopted it, replacing the Fahrenheit scale. Today, it is the standard temperature scale worldwide, except in a few countries like the United States, where Fahrenheit is still commonly used for weather and everyday measurements.

Fahrenheit History: The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit, a German-Polish physicist, in 1724. He based it on three reference points: 0°F as the freezing point of a saltwater brine solution, 32°F as the freezing point of pure water, and 212°F as water’s boiling point at standard atmospheric pressure.

The scale was widely used in English-speaking countries and became the primary temperature system in the United States, while most of the world later adopted the Celsius scale. Despite this shift, Fahrenheit remains popular in the U.S., particularly for weather forecasting and everyday temperature measurements.
