Converting all dimensions from Metric to Imperial all at once

That is really nice work, Dave! I’m just learning and don’t even know what the Layout function is yet. Excited to keep absorbing what I can.

Do you have an online subscription to Fine Woodworking Magazine?

Yes, I do

I don’t either. IMO, very few people work in multiple units at the same time, so the goal would be to support both with a single file instead of creating a separate file for each. But that is a spurious goal, as the equivalent dimensions in other units will almost always be weird and useless for actual creation of the object. For example, 3/4" is close to 19mm, but not an exact match and conversion will lead to clumsy trailing digits and the ~ mark.

You should be able to download plans for some of the featured projects from the magazine. They were done with SketchUp and LayOut.

Yes. The last time I had a client request metric and imperial dimensioned plans I insisted on revising the imperial-dimensioned model and plan to appropriate metric dimensions from which a separate set of metric plans was produced. This avoided potential cumulative rounding errors.

Newbie checking in on this…haha. My thought is you can break down the plans to such a low decimal or fractional amount that the cumulative would be irrelevant, with the exception of something so exact that it would not fall into a standard build category. For example I went to metric 0.0 MM for my vanity project (Or I could’ve went to 64th in standard). To me it doesn’t seem rounding numbers this small would have any negative impact. Am I missing something?

By the way, I used the ‘magic string’ you referenced and it worked like a charm. Only took a minute and everything converts within just a couple clicks. Awesome!

You are missing the fact that the units setting affects display of values, not the values themselves. You can’t make 1 inch equal anything except 2.54cm via the SketchUp units settings no matter what fraction or number of places you choose to display. And 2.54 is not at all a likely size that a sane metric worker would choose!

Off topic question…I don’t seem to get notified when a response comes through. I have my notification settings on under the settings tab. Do you receive any notifications when a new response comes through or is it just silent?

I have it set for email notifications. I get them, but they are often considerably delayed. If I am online, I watch my avatar at upper right of the forum window. It shows the number of replies etc I haven’t looked at yet.

Ok, thanks! Should I delete this info from the thread given it is off topic or it doesn’t really matter?

For just a couple of posts I wouldn’t bother.

noted, ty.

I’m trying to understand your response. Based on the simple ‘bathroom vanity’ model I’m working on it seems that the measurements convert very accurately. What is the display of values you’re referencing?

You have Display Precision set rather coarse for the dimensions in your model.

Here’s with Fractional Units and Display Precision set to 64ths.

And the same dimensions as millimeters.

Do you really plan to work to 64ths or to two places beyond the decimal in millimeters?

And why would someone working in metric want a cabinet 527.05 mm deep even if they are a precision cutting freak? Surely they would choose something else, like 525.0?

At the very least the 0.05 mm would change within a few hours of making the cut.

No, only to the millimeter. And then have a set of fractional plans for quick reference only (since I grew up with the ‘imperial’ system the larger metric measurements are still challenging). But, all cuts will come from metric as to stay uniform. I’m going to reduce minimum increments to mm and 1/8 and see how it goes.

Precision cutting freak… haha, classic.
