Unites

Fast utility for calculate SI and Binary unit prefixes (Units of information). :zap:

Install

Yarn

yarn add unites

NPM

npm install unites

UMD file is also available on unpkg:

<script src="https://unpkg.com/unites/unites.umd.min.js"></script>

You can use the library via window.unites.

Usage

Metric prefix (SI)

Calculates the Metric prefix (SI) and returns the size.

import { si } from 'unites'

si('1M').kilos()
// 1000

si(1, 'M').kilos()
// 1000

Binary prefix

Calculates the Binary prefix and returns the size.

import { binary } from 'unites'

binary('1G').megas()
// 1024

binary(1, 'G').megas()
// 1024

API

Unit prefixes

import { si, binary } from 'unites'

si (value: number | string, symbol?: string): Units
binary (value: number | string, symbol?: string): Units

Measurement units

si('1M').bytes()  // number
si('1M').kilos()  // number
si('1M').megas()  // number
si('1M').gigas()  // number
si('1M').teras()  // number
si('1M').petas()  // number
si('1M').exas()   // number
si('1M').yottas() // number

1. Number values supported: Make sure that symbol param contains k, M, G, T, P, E, Z or Y.
2. String values supported: 1k, 0.5M, 10G, 1T, 1.5P, 0E, 2Z or 0.0001Y
