converter - Convert between different units of measurement #

A Dart library for converting between different units of measurement for various quantities

Usage #

See example/main.dart

final Length l1 = Length(2, 'm'); // 2 metres
final Length l2 = Length(37, 'cm'); // 37 centimetres
final Length l3 = Length(3.7, 'dm'); // 3.7 decimetres

final num l2MagnitudeInInches = l2.magnitudeIn('in');
// l2MagnitudeInInches ~= 14.566929

final Length sum = l1 + l2;
// sum == 2370 millimetres

final Length difference = l1 - l2;
// difference ~= 5.347769 feet

final bool l1EQl2 = l1 == l2;
// l1EQl2 == false

final bool l2EQl3 = l2 == l3;
// l2EQl3 == true

final bool l1GTl2 = l1 > l2;
// l1GTl2 == true

final bool l1LTEl2 = l1 <= l2;
// l1LTEl2 == false
