@johnrob1880/conversions

Utility to ease the pain of converting values from one unit to another. Heavily inspired by ben-ng/convert-units.

Install

Install the conversion library via npm:

npm install @johnrob1880/conversions --save

Install the conversion library via yarn:

yarn add @johnrob1880/conversions

Example

import convert from '@johnrob1880/conversions'
// import conversion systems as needed
import length from '@johnrob1880/conversions/definitions/length'
import volume from '@johnrob1880/conversions/definitions/volume'


let converter = convert().use(volume, length/*, .... */)

// length
console.log(converter.value(1).from('m').to('cm')) // outputs 100

// volume
console.log(converter.value(1).from('gal').to('l', 4 /* optional precision */)) // outputs 3.7854
