Millimeters conversion factor for current projects units.
|
|
|
|
No matter what units the current project uses, this function will always return the conversion factor to millimeters.
|
|
For example, if the current project uses inches, this function will return `(1/25.4)`. If the current project uses millimeters, this function will return `1`.
|
|
**Caution**: This function is only intended to be used when you absolutely MUST have different units in your code than the project settings. Otherwise, it is a bad pattern to use this function.
|
|
We merely provide these functions for convenience and readability, as `10 * mm()` is more readable that your intent is "I want 10 millimeters" than `10 * (1/25.4)`, if the project settings are in inches.
|
|
|
|
```js
|
|
mm() -> number
|
|
```
