Having lots of interrelated units that need to be converted from one to another? Quickconvert to the rescue!

npm i -g quickconvert

Tutorial

Say we have the following units which are taken from this page.

angle.units

q = mm * 4
cm = mm / 10
in = cm / 2.54
pt = in * 72
pc = pt / 12

These are all simple linear equations, following standard JavaScript syntax.

Run quickconvert in a terminal:

quickconvert angle.units > angle.js

Now use it:

const Length = require('./length')
const l = new Length()
l.cm = 4
l.mm // suprise suprise!
l.mm = 5
const l2 = new Length('5px') // works

CLI Usage

quickconvert [--name <name>] file ... 

• name: the name of the JavaScript class. If none is defined, will be derived from the name of the file.

API Reference

This section contains a reference of the generated API. Unit stands for the name of the unit, as defined by the --name-parameter or the name of the definitions file.

12px
2.345rad
1.2em

new Unit(value, type)

Creates a new unit with the given numeric value and the given unit type.

new Length(12, 'px')
new Angle(15, 'grad')

Unit.add(a, b)

Creates a new unit which is the sum of the two given units.

Unit.sub(a, b)

Creates a new unit which is the difference of the two given units.

Unit.neg(a)

Creates a new unit which is the negative of the given unit.

unit.sub(a)

Mutates unit by subtracting the given unit.

unit.add(a)

Mutates unit by adding the given unit.

unit.neg()

Mutates unit by negating it.

const a = new Angle(12, 'deg')
