Quick Start

Get up and running with Univerto in three simple steps

1

Install the package

Add Univerto to your project using your preferred package manager:
npm install univerto
2

Import a converter

Univerto provides modular exports for optimal tree-shaking. Import only what you need:
import { TimeUnitConverter, TIME_UNIT } from 'univerto/time'
Each unit category has its own export path (e.g., univerto/length, univerto/mass) to keep your bundle size minimal.
3

Convert units

Use the fluent API to perform conversions with a clear, readable syntax:
const result = TimeUnitConverter
  .from(24, TIME_UNIT.HOUR)
  .to(TIME_UNIT.DAY)
  .convert()

console.log(result) // 1
The conversion engine uses fraction-based calculations internally, avoiding floating point precision issues common in JavaScript.

Key Features

Built for modern TypeScript applications with precision and performance in mind

Zero Dependencies

Minimal bundle size with no external dependencies. Tree-shakeable exports ensure you only ship what you use.
