node-parse-dimensions

Parse physical object dimensions and convert them into a standardized form.

Example

const pd = require("parse-dimensions");

console.log(pd.parseDimension("4in x 5in"));
// { original: '4in x 5in', unit: 'mm', width: 101.6, height: 127 }

console.log(pd.parseDimension("4.2cm x 5.1cm"));
// { original: '4.2cm x 5.1cm', unit: 'mm', width: 42, height: 51 }

You can see a full list of all the types of dimension strings handled in the test file.

Installation

npm install parse-dimensions

API

parseDimension(dimensionString, [flip])

Parse a string that holds some dimensions and returns an object representing the dimensions. By default it assumes that the width is first. Pass a boolean as the second argument to assume the height is first.

parseDimensions(dimensionsString, [flip])

Parse a string that holds a set of dimensions and returns an array of objects representing the dimensions. It assumes that the dimensions are separated by semicolons by default.

convertNumber(number, fromUnit, toUnit)

Convert a number from one dimension unit to another. For example: convertNumber(10, "mm", "cm") will return 1.

convertDimension(dimensionObject, toUnit)

Given a dimension object (as produced by parseDimension) convert it to use a different dimension. Returns the modified dimension object.
