For the gauge and indicator elements, authors can indicate
that numbers should be converted from one unit to another. This is
helpful when the data is in a certain set of units, but you want to display it in another set of units without changing it.
There are many specific use cases for this:

- Length conversions (for example, miles to kilometers)
- Weight conversions (for example, pounds to kilograms)
- Temperature conversions (for example, degrees Celsius to Fahrenheit)
- Power conversions (for example, watts to kilowatts)
- Number conversions (for example, decimal to percent)

In general, value conversion can be represented by the equation y = mx + b. Using this formula, a number can be converted to any other number along a straight line.

- x = number to be converted
- m = conversion factor (slope) to be applied to x
- b = offset to be applied (y-axis intercept)
- y = number that is displayed in the dashboard

The Value conversion setting is on the Data tab for the indicator and gauge. After you enable Value Conversion, two additional settings appear: Factor and Offset.

The Factor setting represents the m in the equation y = mx + b and the Offset setting represents the b.

The following table provides examples of numbers to enter in the Factor and Offset settings to perform value conversions.

Type of conversion | Factor value | Offset value |

Number—Decimal to percent | 100 | Leave as 0 |

Temperature—Degrees Celsius to degrees Fahrenheit | 1.8 | 32 |

Weight—Pounds to kilograms | 0.45359237 | Leave as 0 |

You can't enter fractions in the Factor setting (for example, 5/9). You can only enter positive and negative decimals and whole numbers.
