Unit Explanations
Celsius°C
Source UnitCelsius, denoted by the symbol °C, is a scale and unit of measurement for temperature. It is named after the Swedish astronomer Anders Celsius, who developed a similar temperature scale. In the Celsius scale, the freezing point of water is 0 degrees, and the boiling point is 100 degrees under standard atmospheric pressure. This makes it especially useful for scientific calculations and everyday temperature measurements as it aligns closely with the metric system. The Celsius scale is widely used around the world, with the exception of some countries like the United States, which predominantly uses Fahrenheit.
Current Use
The Celsius scale is the most widely used temperature scale in the world today. It is used in most countries for daily temperature measurements. In scientific contexts, it is used alongside the Kelvin scale, which is the SI unit for temperature. The Celsius scale's straightforward alignment with the metric system makes it an ideal choice for educational, scientific, and meteorological purposes.
Fun Fact
The Celsius scale was initially reversed, with 0 as boiling point and 100 as freezing point.
Fahrenheit°F
Target UnitFahrenheit is a temperature measurement scale where the freezing point of water is defined as 32 degrees Fahrenheit (°F) and the boiling point as 212°F at standard atmospheric pressure. This scale divides the interval between the freezing and boiling points of water into 180 equal parts. It is predominantly used in the United States and some Caribbean nations for non-scientific applications, making it one of the few non-metric temperature scales still in use.
Current Use
Today, the Fahrenheit scale is primarily used in the United States and a few Caribbean countries for non-scientific applications, such as weather forecasts, cooking, and air conditioning. It is less commonly used in scientific contexts where the Celsius scale or Kelvin scale is preferred.
Fun Fact
The Fahrenheit scale was the first widely used temperature scale.
Convert Celsius to Fahrenheit (°C to °F)
Convert Celsius (°C) to Fahrenheit (°F). The quick mental trick? Double it and add 30. (20°C x 2 = 40 + 30 = 70°F). The exact formula is slightly different (x1.8 + 32), but the trick works well for weather.
Multiply by 1.8 (9/5) and add 32. For example, 30°C = 86°F.

The Celsius scale is widely used around the world, with the exception of some countries like the United States, which predominantly uses Fahrenheit.
History & Origin
The Celsius scale was developed by Swedish astronomer Anders Celsius in 1742. Originally, Celsius devised his scale with 0 as the boiling point of water and 100 as the freezing point, which was later inverted by Carl Linnaeus in 1744 to its current form. This scale quickly became popular due to its straightforward 100-degree interval between the key physical phenomena of freezing and boiling water, which made it intuitive and easy to use, particularly for scientific work.
Etymology: The term 'Celsius' comes from the surname of Anders Celsius, the inventor of this temperature scale.

Fahrenheit is a temperature measurement scale where the freezing point of water is defined as 32 degrees Fahrenheit (°F) and the boiling point as 212°F at standard atmospheric pressure.

It is predominantly used in the United States and some Caribbean nations for non-scientific applications, making it one of the few non-metric temperature scales still in use.
History & Origin
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit, a Polish-German physicist, in 1724. He based his scale on three reference points: the lowest temperature he could achieve with a mixture of ice, water, and ammonium chloride (0°F), the freezing point of water (32°F), and the average human body temperature (approximately 96°F at the time, now adjusted to 98.6°F).
Etymology: The term 'Fahrenheit' originates from Daniel Gabriel Fahrenheit's last name.
Current Use
Today, the Fahrenheit scale is primarily used in the United States and a few Caribbean countries for non-scientific applications, such as weather forecasts, cooking, and air conditioning. It is less commonly used in scientific contexts where the Celsius scale or Kelvin scale is preferred.
💡 Fun Facts
- •The Fahrenheit scale was the first widely used temperature scale.
- •Fahrenheit initially set 0°F as the lowest temperature he could create in his lab.
- •Fahrenheit's original human body temperature scale was adjusted from 96°F to 98.6°F.
