Is it possible to set in preferences metric system. Really, no one care about inches and feet except you guys. Thanks

Thanks!

area.swift 
// the height and width of a wall
let height = 120.0 // in inches
let width = 144.0 // in inches

let areaInFeet = height * width

Hello Adil:

I this a question or a statement ?

On regards of the metric system, I don't think what's being taught in this video has anything to do with the metric system, but to use calculations for different things as this is just an example of the capabilities of swift, all you have to do is use some math to calculate areas. You can use meters, or feet, which ever you like to satisfy your project needs.

Happy Coding.
