# Metric Measurements Answered

While I completely understand using inches in this tutorial, can I suggest adding the metric equivalent as well in the steps? As someone from the rest of the world that uses metric, switching to inches makes no sense (for the same reasons that you *do* use inches), and having to stop what I'm doing to convert to metric takes me out of the whole flow that I've got going on..

Ask and you shall receive! It bears noting that this is the only project in the class that's designed in imperial units, all the other projects are in millimeters. I almost always use metric when it comes to 3D printing because the units make more sense at a small scale, and the clean division by 2,3,4,6, and 8 are less important for small scale objects.

In architecture and furniture, though, it might surprise you to find out that a lot of architects and designers (even those brought up with the metric system) still prefer imperial because they are anthropocentric. 6" is about the length of a hand, 18" is about the length from your elbow to your fingertips, 12" is about the length of a man's foot with shoes on, etc. The division by 2,3,4,6,8, and 12 might seem trivial (of course you can divide anything by anything in a base-10 system), but you get messy numbers and repeating decimals this way. Base 12 is what you use in musical notation, and concepts like rhythm, pattern, and symmetry lend themselves nicely to this kind of math.

Awesome - thanks very much for that.. (You obviously feel quite passionatly about imperial measurements! :)
