But will it? In the UK 2x4, 2x2 etc is still commonly available, but it's 50x100mm. Probably has been for 30 years but only sold as 50x100 for ten or less. Metricating timber was easy because no one's going to notice or care if they get 25mm instead of each inch. Metals, fastenings, pipes etc converted much slower because metric was often incompatible sizes without adapters. > Which actually measures 1-1/2" by 3-1/2", Isn't that because it's 2x4 before planing. cut lumber would be actually 2x4.

> Isn't that because it's 2x4 before planing. cut lumber would be actually 2x4. It used to be, but now we're more efficient in our rough cutting and a 2x4 you buy was never actually a full 2x4.

And cut lengths of timber and sheet materials are usually multiples of 30cm but many people will order "8 foot" rather than 2.4m. Likewise joist and stud centres. However you can also get 3m or 5m, for example. Of course, most houses in the UK were built pre-metric system, so rooms will mostly be sized in feet, if they are in round units at all.
