About The Project

Screenshot 1

Working with different units of measurements can be a pain. This project provides a Dart Library with basic classes for working with various measurement units. So far the supported measurements include:

  • x Length
  • x Mass
  • x Area

Getting Started


This package can only be used by other dart projects. If this is your first dart project, see the following pages to help you get started:


Add measurements as a dependency in your pubspec.yaml file.



import 'package:measurements/measurements.dart';

void main(List<String> arguments) async {
  Length heightOfEverest = Length.fromMetres(8848.0);
  print("Height of Everest (in metres): ${heightOfEverest.inMetres}.");
  print("Height of Everest (in kilometres): ${heightOfEverest.inKilometres}.");
  print("Height of Everest (in yards): ${heightOfEverest.inYards}.");
  print("Height of Everest (in miles): ${heightOfEverest.inMiles}.");


import 'package:measurements/measurements.dart';

void main(List<String> arguments) async {
  Area a = Area.fromAcres(87.0);
  Area b = Area.fromAcres(43.0);
  print("a + b is ${(a + b).inAcres} acres.");
  print("a - b is ${(a - b).inAcres} acres.");
  print("a * 4 is ${(a * 4).inAcres} acres.");
  print("a / 4 is ${(a / 4).inAcres} acres.");


import 'package:measurements/measurements.dart';

void main(List<String> arguments) async {
  Mass elephantWeight = Mass.fromKilograms(5400);
  Mass zebraWeight = Mass.fromKilograms(380);
  if (elephantWeight == zebraWeight) {
    print("An elephant and a Zebra have the same weight.");
  } else if (zebraWeight < elephantWeight) {
    Mass difference = elephantWeight - zebraWeight;
    print("An elephant is ${difference.inPounds} pounds heavier than a zebra.");
  } else {
    Mass difference = zebraWeight - elephantWeight;
    print("A Zebra is ${difference.inPounds} pounds heavier than an elephant.");


We are hoping to provide the following measurements in the near future:

  • DataTransferRate
  • DigitalStorage
  • Energy
  • Frequency
  • Pressure
  • Speed
  • Temperature
  • Volume

See the open issues for a list of other proposed features (and known issues).
