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

### 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.");
}
}
``````

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).
