How To Convert Celsius To Fahrenheit

The easy method of converting Celsius to Fahrenheit is to multiply the Celsius temperature by 9, divide by 5, then add 32. For example, 20°C × 9 ÷ 5 + 32 = 68°F.

Above, we’ve also listed some handy Celsius to Fahrenheit (and vice versa) conversions above. 

How To Convert Fahrenheit To Celsius

Converting Fahrenheit to Celsius can also be done with a simple calculation. Subtract 32 from the Fahrenheit temperature, multiply by 5, then divide by 9. For example, 68°F − 32 × 5 ÷ 9 = 20°C.

Why Do We Have Both Fahrenheit And Celsius?

Here in the UK, we use Celsius, while other countries such as the United States use Fahrenheit.

The two scales were developed independently in the early 18th century. Daniel Fahrenheit introduced his scale in 1724, while Anders Celsius proposed his in 1742. 

Most of the world adopted Celsius as part of the metric system, but the United States and a small number of other countries continue to use Fahrenheit.

What’s The Difference Between Celsius, Centigrade And Fahrenheit?

Celsius, centigrade and Fahrenheit are all temperature scales, but they differ in how they define degrees. Celsius and centigrade actually refer to the same scale; however,  ‘centigrade’ is the older name, meaning “divided into 100 degrees,” because it sets 0° as the freezing point of water and 100° as the boiling point under standard conditions.

In modern times, the term Celsius (named after astronomer Anders Celsius) is preferred, especially here in Nottinghamshire, where the Lee Jackson Air Conditioning team is based.  

Fahrenheit, on the other hand, uses a different system, where water freezes at 32° and boils at 212°, making the interval between those points 180 degrees. As a result, Fahrenheit degrees are smaller and more granular, while Celsius (centigrade) is simpler and widely used in science and most countries worldwide.

What Is Room Temperature?

‘Room temperature’ is a colloquial saying we use a lot, especially in terms of serving food. The term is used to loosely define an ideal indoor temperature, which is considered around 20°C (68°F). However, in some instances, room temperature can be anywhere between 15°C and 25°C (59°F to 77°F) depending on the context.

Within air conditioning installations, room temperature can have a broader meaning, since it can refer to zone climate control, whereby every room of your home has a specific room temperature that your air conditioning is set to. 

What Is A Comfortable Room Temperature?

Most people find a room temperature of between 18°C and 21°C (64°F to 70°F) comfortable for living and sleeping. That said, at Lee Jackson, we find that what our customers deem to be an ‘ideal temperature’ can vary depending on the season, the room’s purpose and personal preference.
