Origins of Celsius and Fahrenheit: How the Temperature Scales Came to Be

15 Celsius to Fahrenheit

Temperature measurement is an important part of our everyday lives. It affects everything from weather forecasts to scientific studies. Celsius and Fahrenheit, two of the most well-known temperature scales, have interesting histories that show both the scientific progress and the practical needs of their times.

In this piece, we look at the interesting stories behind how these temperature scales came to be and show how their creators used creativity and logic to make them. From Anders Celsius’s careful studies of how water moves to Daniel Gabriel Fahrenheit’s new way of measuring temperature, we find out where these scales came from and how they changed how we think about and measure temperature. Come with us on a trip through time to learn about how temperature was measured and how the Celsius and Fahrenheit scales came to be.

Let’s Start with Anders Celsius Studies

Celsius – Its History and Importance

Anders Celsius, a Swedish scientist, came up with the Celsius scale, which is also called the centigrade scale, in the early 1800s. Celsius made his scale based on the freezing and boiling points of water. At normal atmospheric pressure, 0 degrees Celsius (°C) is the freezing point of water, and 100 degrees Celsius is the boiling point of water.

History Of Anders Celsius?

Anders Celsius was born November 27, 1701, in Uppsala, Sweden. He was a famous Swedish astronomer, physicist, and mathematician. The most important thing he did for science was to come up with the Celsius temperature scale, but he also did study in many other areas.


  • Scientists were in Anders Celsius family. His father, Nils Celsius, taught astronomy at Uppsala University, and his grandpa, Magnus Celsius, was a famous mathematician.
  • Anders Celsius was good at math and science from a young age. This was helped by the fact that he grew up in an academic home.
  • He began his schooling at Uppsala University, where he studied astronomy, math, and physics.

What is the Meaning of Celsius?

The Celsius scale, also called the centigrade scale, is based on the fact that water freezes at 0° and boils at 100°.

Why is the Scale Called Celsius?

36 Celsius to Fahrenheit

Anders Celsius came up with the Celsius temperature scale, which is named after him. The scale was made by Anders Celsius, a Swedish scientist, physicist, and mathematician, in the early 1800s.

Water Scale

When Celsius first made his scale, the freezing point was 100 degrees and the boiling point was 0. Later, the scale was changed to its current form so that it would be the same as other temperature scales. The Celsius scale has become the usual way to measure temperature in many parts of the world because it is easy to use and matches how water behaves.

The Celsius scale is used everywhere that uses the metric system of units, and scientists use it everywhere.

Now that we have understood everything about Anders Celsius and his geniuses, now let’s have a look at how Fahrenheit was introduced to the world.

Fahrenheit – Its History and Importance

In the early 1800s, a Polish-German scientist named Daniel Gabriel Fahrenheit came up with the Fahrenheit scale. Unlike Celsius, Fahrenheit’s scale wasn’t based on basic scientific principles at first. Instead, it was based on real temperature points that he had seen.

History Of Daniel Gabriel Fahrenheit?

Daniel Gabriel Fahrenheit was born on May 24, 1686, in Gdansk, which was part of the Polish-Lithuanian Commonwealth at that time (now in Poland). He was a physicist, engineer, and instrument maker who made important contributions to measuring temperature. His name will always be linked to the Fahrenheit temperature scale. He created and introduced it to the scientific community.


  • Fahrenheit was raised in a family of merchants, and his father’s passion in commerce and trade shaped Fahrenheit’s early schooling.
  • When he was still young, both of his parents passed away, and he relocated to Amsterdam. There, he followed his passion in science and started working as an instrument builder.

What is the Meaning of Fahrenheit?

It’s about a temperature scale where water boils at 212 degrees and freezes at 32 degrees above zero.

Fahrenheit said that 0 degrees Fahrenheit (°F) was the coldest temperature he could reach by mixing ice and salt. He called this temperature “zero degrees cold.” Then, he decided that a person’s average body temperature is 100 degrees Fahrenheit. Later, Fahrenheit changed his scale so that the point at which water freezes is 32 degrees Fahrenheit and the point at which water boils is 212 degrees Fahrenheit.

Why is the Scale Called Fahrenheit?

Daniel Gabriel Fahrenheit made the Fahrenheit temperature scale, so it is named after him. Fahrenheit created the scale in the early 1800s. He was a Polish-German scientist, engineer, and instrument maker.

Imperial Scale?

The Fahrenheit scale became famous in English-speaking countries, especially the US, and is still used a lot in those places today. Due to its simplicity and fit with the metric system, the Celsius scale is more often used in science and foreign settings. However, in some countries, the Fahrenheit scale is still used for everyday temperature measurements.

Celsius and Fahrenheit

For conversion of Fahrenheit to Celsius or vice versa, read the formula below and view some examples too.

The formula for converting Celsius to Fahrenheit is: °F = (°C 9/5) plus 32

The formula for converting Fahrenheit to Celsius is: °C = (°F – 32) 5/9

How to utilize these formulas:

Converting Celsius to Fahrenheit.

36 Celsius to Fahrenheit

  • The temperature is measured in Celsius (°C).
  • It is multiplied by 9/5 (or 1.8).
  • Add 32 to the outcome.

Converting Fahrenheit to Celsius.

36 Celsius to Fahrenheit

  • The temperature is measured in Fahrenheit (°F).
  • Remove 32 degrees from the temperature.
  • Multiply the result by 5/9 (or approximately 0.5556) to get the answer.

Here are some examples:

Example 1: Celsius to Fahrenheit.

 Convert 15 Celsius to Fahrenheit.

 °F = (15 × 9/5) + 32 °F = (15 × 1.8) + 32 °F = 15 + 32 °F = 59

Therefore, 15 Celsius to Fahrenheit is equal to 59 Degree Fahrenheit.

Example 2: Celsius to Fahrenheit

 Convert 36 Celsius to Fahrenheit

°F = (36 × 9/5) + 32 °F = (36 × 1.8) + 32 °F = 64.8 + 32 °F = 59

Therefore, 36 Celsius to Fahrenheit is roughly equivalent to 59 degrees Fahrenheit.

These straightforward formulas enable you to convert temperatures between Celsius and Fahrenheit with ease.
