The Temperature Converter is an online tool that allows you to convert temperatures from one scale to another, quickly and easily. With this converter, you can convert temperatures to Celsius, Fahrenheit, Kelvin, Rankine, Réaumur, Delisle and Newton.

The tool is simple to use: just enter the temperature you want to convert and select the source scale and target scale. The converter will then automatically calculate the converted value at all other scales.

For example, if you have a temperature of 25 degrees Celsius and you want to know what the equivalent temperature is in Fahrenheit, just select the Celsius scale as the source scale, the Fahrenheit scale as the destination scale, and enter the value of 25 degrees. The converter will then display the result of 77 degrees Fahrenheit in addition to the other temperature scales.

## Temperature Scales and their calculations

### Celsius (°C)

It is the most common scale in the world, and is used in most countries. It was created by the Swedish astronomer Anders Celsius in 1742. The Celsius scale defines the freezing point of water at 0 degrees Celsius and the boiling point at 100 degrees Celsius. The formula for converting Celsius to other scales is as follows:

- Fahrenheit: (C × 1,8) + 32
- Kelvin: C + 273,15
- Rankine: (C + 273,15) × 1,8
- Réaumur: C × 0,8
- Delisle: (100 – C) × (3/2)
- Newton: C × (33/100)

### Fahrenheit (°F)

It is the most common scale in the United States. It was created by the German physicist Daniel Gabriel Fahrenheit in 1724. The Fahrenheit scale defines the freezing point of water at 32 degrees Fahrenheit and the boiling point at 212 degrees Fahrenheit. The formula for converting Fahrenheit to other scales is as follows:

- Celsius: (F − 32) ÷ 1,8
- Kelvin: (F − 32) ÷ 1,8 + 273,15
- Rankine: F + 459,67
- Réaumur: (F − 32) ÷ 2,25
- Delisle: (212 − F) × (5/6)
- Newton: (F − 32) ÷ 2,25 × (33/100)

### Kelvin (K)

It is the International System of Units (SI) unit of temperature. It was created by Irish physicist and mathematician William Thomson, also known as Lord Kelvin, in 1848. The Kelvin scale defines absolute zero at -273.15 degrees Celsius. The formula for converting Kelvin to other scales is as follows:

- Celsius: K − 273,15
- Fahrenheit: (K − 273,15) × 1,8 + 32
- Rankine: K × 1,8
- Réaumur: (K − 273,15) × 0,8
- Delisle: (373,15 − K) × (3/2)
- Newton: (K − 273,15) × (33/100)

### Rankine (°R)

It is the absolute temperature scale of the English unit system. It was created by the Scottish engineer and mathematician William John Macquorn Rankine in 1859. The formula for converting Rankine to other scales is as follows:

- Celsius: (R – 491,67) × (5/9)
- Fahrenheit: R – 459,67
- Kelvin: R × (5/9)
- Réaumur: (R – 491,67) × (4/9)
- Delisle: (671,67 – R) × (5/6)
- Newton: (R – 491,67) × (11/60)

### Réaumur (°Ré)

The Réaumur scale was created by the French physicist René Antoine Ferchault de Réaumur in 1731. On this scale, the freezing point of water is defined as 0°Ré and the boiling point of water is defined as 80°Ré. The formula for converting Réaumur to other scales is as follows:

- Celsius: °Ré × 1,25
- Fahrenheit: °Ré × 2,25 + 32
- Kelvin: °Ré × 1,25 + 273,15
- Rankine: °Ré × 2,25 + 491,67
- Delisle: (80 − °Ré) × 1,875
- Newton: °Ré × 0,4125

### Delisle (°From)

The Delisle scale was created by the French physicist Joseph-Nicolas Delisle in 1732. On this scale, the freezing point of water is defined as 150°De and the boiling point of water is defined as 0°De. The formula for converting Delisle to other scales is as follows:

- Celsius: (100 − °De) × 2/3
- Fahrenheit: (212 − °De) × 5/6
- Kelvin: 373,15 − °De × 2/3
- Rankine: (671,67 − °De) × 5/6
- Réaumur: (80 − °De) × 0,9375
- Newton: (33 − °De) × 22/50

### Newton (°N)

The Newton scale was created by the English physicist and mathematician Isaac Newton in 1701. On this scale, the freezing point of water is defined as 0°N and the boiling point of water is defined as 33°N. The formula for converting Newton to other scales is as follows:

- Celsius: °N × 100/33
- Fahrenheit: °N × 60/11 + 32
- Kelvin: °N × 100/33 + 273,15
- Rankine: °N × 132/11 + 491,67
- Réaumur: °N × 80/33
- Delisle: 33 − °N × 50/11
