Description:

converter

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
Length
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 l2ValueInInches = l2.valueIn('in');
// l2ValueInInches ~= 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

Time
final Time t1 = Time.si(86400); // 86400 seconds
final Time t2 = Time(24, 'h'); // 24 hours
final Time t3 = Time(1500, 'min'); // 1500 minutes

final num t3ValueInDays = t3.valueIn('d');
// t3ValueInDays ~= 1.041667

final Time sum = t1 + t2;
// sum == 2880 minutes

final Time difference = t3 - t2;
// difference == 3600 seconds

final bool t1EQt2 = t1 == t2;
// t1EQt2 == true

final bool t2EQt3 = t2 == t3;
// t2EQt3 == false

final bool t3GTt2 = t3 > t2;
// t3GTt2 == true

final bool t3LTEt2 = t3 <= t2;
// t3LTEt2 == false
