CSSNumericValue: to() method

Note: This feature is available in Web Workers.

The to() method of the CSSNumericValue interface converts a numeric value from one unit to another.

Syntax

to(unit)

Thrown if an invalid unit was passed to the method.

Thrown if:

The CSSNumericValue on which the method is being called can't be resolved to a single value and type. This might occur if the value is calculated from a variable when the value of that variable can't be known in the context.
The value can't be converted to the new unit because it's not of the same category. For example, you can't convert meters to seconds.

// Prints "0.608542cm"
console.log(CSS.px("23").to("cm").toString());
