# Temperature Converter

This converter will change a temperature value between degrees Celsius, degrees Fahrenheit, degrees Kelvin, and degrees Rankine.

Additionally, a conversion scale appropriate for each converted temperature will be shown by this tool.

Absolute zero is the lowest temperature that may exist: zero Kelvin (0 K), or -273.15 °C, -459.67 °F, or 0 °R. Despite this, you can still convert negative values to Kelvin units with this tool.

1. In the upper input box, enter the temperature reading you want to convert.
2. Choose the corresponding units from the upper selection list for the temperature input above.
3. Choose the temperature units you want to use for the conversion from the lower selection list.
4. The lower text box will show the converted temperature.

## Conversion Equations

This temperature converter uses the following formulas to convert between different temperature scale units:

°C is calculated as (°F - 32) x 5/9 °C, K, and (°R x 5/9), respectively, in Celsius.

Fahrenheit (°F) is calculated as follows: (°C x 9/5) + 32 °F = ((K - 273.15) x 9/5) + 32 °F = (°R - 459.67)

## Use of Calculators

The formula to convert temperatures varies based on the two temperature ranges you're converting between.

For instance, we enter our data into the formula as follows to convert 50 degrees Celsius (centigrade) to Fahrenheit: F = C * 9/5 + 32

F = 50 * 9/5 + 32 F = 90 + 32 \sF = 122

122 degrees Fahrenheit is equivalent to 50 degrees Celsius.

## Why is it so difficult to convert between Fahrenheit and Celsius?

Most of the things we measure—length, width, time, etc.—have one thing in common: all of their values begin at zero. We can readily translate zero of any of those units into another type of unit because we all know precisely how long zero centimetres or inches are. There are no millimetres, metres, or inches. Using inches and centimetres as an example, we need to add one inch to go from 0 to 1 inch. So far, so evident.

Similar to this, all it takes to go from 0 centimetres to 1 centimetre is to add 1 centimetre. The quantity of space we add makes no difference whether we add one inch or one centimetre. The conversion from an inch to a centimetre is 2.54 centimetres to an inch. As a result, adding 1 inch is equivalent to adding 2.54 centimetres. Temperature units are not constructed in the same straightforward manner since they do not all start in the same place at zero, even though the conversion formula between the two is pretty straightforward (in = cm * 0.39370). Since Fahrenheit and Celsius were established before we knew the location of absolute zero, Fahrenheit, Celsius, and Kelvin all begin from different values. Converting between them would be more straightforward if we set absolute zero as 0°F, 0°C, and 0K.

Because there is no common zero point for these temperature measurements, we must add or subtract an offset before performing division or multiplication. It's not a challenging extra step, but it does seem like it could be confusing.
