Usage #
A simple usage example:
import 'package:unities_helper/unities_helper.dart';

main() {
/// Convert 25°C into Fahrenheit
final temperature = convert<Temperature>(
Temperature.celcius, // from
Temperature.fahrenheit, // to
25, // value
);
print(temperature);
}

Using extension methods #
Instead of using convert + unit name, you can use num.as + unit name. For example, if I want to convert mass, I can do it with two ways:
Using convert method #
main() {
final mass = convertMass(Mass.kilogram, Mass.gram, 10);
print(mass);
}
copied to clipboard
Using extension methods #
main() {
final mass = 10.asMass(Mass.kilogram).toGram;
print(mass);
}
copied to clipboard
Both will print the same results. You can use extension methods with the following conversion types:

✔️ Area
❌ Color
✔️ Data Transfer Rate
✔️ Digital Storage
✔️ Energy
✔️ Frequency
✔️ Fuel Economy
✔️ Length
✔️ Mass
✔️ Plane Angle
✔️ Pressure
✔️ Speed
✔️ Temperature
✔️ Time
✔️ Volume
