## User Guide

This conversion tool will convert the difference between two temperature readings or an incremental change in temperature to degree Celsius, degree Fahrenheit, Kelvin or degree Rankine measurement units.

A temperature difference, also known as a delta temperature (ΔT), is the result of subtracting two separate isolated temperature readings, or measuring the amount of temperature rise or fall.

Unlike the conversion of readings between two different temperature scales, the conversion for a temperature difference is directly proportional from one unit to another.

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

- Enter the temperature difference or change 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 difference will display in the lower answer box.

### Conversion Formulas

The following formulas are used by this temperature difference converting tool to convert a temperature increment or difference from one unit to the other:

#### Celsius

°C = °F x 5/9

°C = K

°C = °R x 5/9

#### Fahrenheit

°F = °C x 9/5

°F = K x 9/5

°F = °R

#### Kelvin

K = °C

K = °F x 5/9

K = °R x 5/9

#### Rankine

°R = °C x 9/5

°R = °F

°R = K x 9/5

### Kelvin SI Metric Prefix Temperature Units

These temperature units belong to the SI measurement systems and are derived from the kelvin unit, which is the base SI unit for temperature measurement.
