# What does a Fahrenheit scale measure

## Convert degrees Fahrenheit to Degrees Celsius and vice versa

### History of the origin of Fahrenheit and Celsius

A Swedish astronomer by the name of Anders Celsius presented the temperature scale that would later be widely used. He used the temperature at which water freezes and boils as a fixed point. The result is a scale from 0 ° C to 100 ° C. After his death, his friend von Linné introduced the modern Celsius scale.

Fahrenheit came about in a completely different way. The Dane Olé Rømer measured the lowest temperature he could produce. He set this as a fixed point of 0 ° Fahrenheit and wanted to avoid negative numbers. As a top fixed point, he set body temperature at 100 ° F. This is how the scale came about that is still in use today. This scale is still the standard today, especially in America.

### Ratio of Fahrenheit to Celsius

It is difficult for a German to imagine Fahrenheit as 0 ° F equals -17.8 ° C. 100 ° F corresponds to 37.8 ° C. The 100 ° steps are distributed differently in Fahrenheit than in Celsius. One ° F corresponds to approx. 0.56 ° C. So it's hard to imagine what temperatures feel like for those who are unfamiliar with the particular system.

### Formulas and help for converting Fahrenheit and Celsius

There are a few simple rules of thumb and tips to get an idea about Fahrenheit:

• The body temperature of 37 ° Celsius corresponds to approx. 100 ° Fahrenheit. So you can simply link these two numbers in your head.
• 61 ° F is 16 ° C - as a German you only have to remember the 16 and the other way around it is 61 ° F
• 82 ° F is 28 ° C - it's the same here. If you remember the 28, you know that at around 80 ° F you are well dressed with a T-shirt.

Of course there are also official formulas for conversion. However, these are a bit bulky and therefore extremely unsuitable for everyday use:

• ° C = (° F - 32) * 5/9 (from Fahrenheit to Celsius)
• ° F = ° C * 1.8 + 32 (from Celsius to Fahrenheit)
