How to use

Import

This line of code should be added at the begin of the code. In this example we import the enum LengthUnit and the function convertUnits.

import { LengthUnit, convertUnits } from './@erboladaiorg/et-numquam';

Angle

const milliradians = 10;
const circles = convertUnits(milliradians, AngleUnit.MILLIRADIAN, AngleUnit.CIRCLE);
console.log(`${milliradians} milliradians are ${circles} circles`); // Output: "10 milliradians are 0.0015915494309189536 circles"
