Measurement Unit Converter
It is a npm package for converting units, including: Angle, Area, Length, Mass, Speed, Temperature, Time, and Volume.
Adding the following function:
- Solve the problem of floating-point precision after unit conversion
Install
npm install measurement-unit-converter
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 './measurement-unit-converter';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"
