Construct a length from a number of meters.

height : Length
height =
    Length.meters 2

Convert a length to a number of meters.

Length.feet 1 |> Length.inMeters
--> 0.3048

Construct a length from a number of angstroms.

Length.angstroms 1
--> Length.meters 1e-10

Convert a length to a number of angstroms.

Length.nanometers 1 |> Length.inAngstroms
--> 10

Construct a length from a number of nanometers.

Length.nanometers 1
--> Length.meters 1e-9

Convert a length to a number of nanometers.

Length.microns 1 |> Length.inNanometers
--> 1000

Construct a length from a number of microns (micrometers).

Length.microns 1
--> Length.meters 1e-6

Convert a length to a number of microns (micrometers).

Length.millimeters 1 |> Length.inMicrons
--> 1000

Length.thou 5
--> Length.inches 0.005

Convert a length to a number of thou (thousandths of an inch).

Length.millimeters 1 |> Length.inThou
--> 39.37007874015748

Construct a length from a number of inches.

Convert a length to a number of inches.

Construct a length from a number of feet.

Convert a length to a number of feet.

Construct a length from a number of yards.

Convert a length to a number of yards.

Construct a length from a number of miles.

Convert a length to a number of miles.

Construct a length from a number of CSS pixels, defined as 1/96 of an inch.

Note the difference between this function and Pixels.pixels. Length.cssPixels 1 is equivalent to Length.inches (1 / 96) or approximately Length.millimeters 0.264583; it returns a length in real world units equal to the (nominal) physical size of one CSS pixel.

In contrast, Pixels.pixels 1 simply returns an abstract "1 pixel" value. You can think of Length.cssPixels 1 as a shorthand for

Pixels.pixels 1
    |> Quantity.at_
        (Pixels.pixels 96
            |> Quantity.per (Length.inches 1)
        )

That is, Length.cssPixels 1 is the size of 1 pixel at a resolution of 96 DPI.

Convert a length to a number of CSS pixels.

Construct a length from a number of points, defined as 1/72 of an inch.

Convert a length to a number of points.

Construct a length from a number of picas, defined as 1/6 of an inch.

Convert a length to a number of picas.

Construct a length from a number of astronomical units (AU). One AU is approximately equal to the average distance of the Earth from the Sun.

Convert a length to a number of astronomical units.

Construct a length from a number of parsecs.

Convert a length to a number of parsecs.

Construct a length from a number of light years. One light year is the distance traveled when moving at the speed of light for one Julian year.
