## User Guide

This conversion tool will convert a temperature value from and to degree Celsius, degree Fahrenheit, Kelvin or degree Rankine measurement units.

This tool will also display a conversion scale applicable to each converted temperature.

The lowest possible temperature is zero Kelvin (0 K), -273.15 °C, -459.67 °F, or 0 °R and this is called absolute zero. Despite this you can still use this tool to convert negative values in Kelvin units.

- Enter the temperature reading you would like to convert in the upper input box.
- Select the corresponding units from the upper shortcut buttons or pull down options.
- Select the temperature units from the lower shortcut buttons or pull down options.
- The converted temperature will display in the lower answer box.

### Conversion Formulas

The following formulas are used by this temperature converting tool to convert from one temperature scale unit to the other:

#### Celsius

°C = (°F - 32) x 5/9

°C = K - 273.15

°C = (°R x 5/9) - 273.15

#### Fahrenheit

°F = (°C x 9/5) + 32

°F = ((K - 273.15) x 9/5) + 32

°F = °R - 459.67

#### Kelvin

K = °C + 273.15

K = ((°F - 32) x 5/9) + 273.15

K = °R x 5/9

#### Rankine

°R = (°C + 273.15) x 9/5

°R = °F + 459.67

°R = K x 9/5

### Celsius to Fahrenheit

*A degree Celsius is equal to how many degree Fahrenheit?*

The conversion between degrees Celsius and degrees Fahrenheit is not directly proportional, so each conversion has to be calculated independently, e.g. 1 degC = 33.8 degF, but 2 degC does not equal 67.6 degF.

The conversion can be easily carried out using a calculator by multiply the Celsius value by 9/5 and then adding 32 to convert to Fahrenheit temperature units.

Fahrenheit = (Celsius x 9/5) + 32

### 0-600°K to °C

*What does a 0-600K temperature range look like in degrees C?*
