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"

Area

const squareInches = 10;
const squareMillimeters = convertUnits(squareInches, AreaUnit.SQUARE_INCH, AreaUnit.SQUARE_MILLIMETER);
console.log(`${squareInches} square inches are ${squareMillimeters} square millimeters`); // Output: "10 square inches are 6451.6 square millimeters"

Speed

const kilometersPerHour = 10;
const metersPerSecond = convertUnits(pints, SpeedUnit.KILOMETER_PER_HOUR, SpeedUnit.METER_PER_SECOND);
console.log(`${kilometersPerHour} kilometers per hour are ${metersPerSecond} meters per second`); // Output: "10 kilometers per hour are 2.7778 meters per second"
