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

Built With #

Getting Started #

Prerequisites #

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:

Installation #

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

Usage #

Conversions:

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}.");
}

Calculations:

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.");
}

Comparisons:

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.");
  }
}

Roadmap #

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).
