Is it possible to reset Cura from mm to inches?

I'm stumped.  I live in a country where we don't use mm or cm or anything but inches and feet.  How can I reset Cura to inches?

You can't. You can install a plugin that will let you scale a loaded model by 25.4 (from inches to mm), but there is no way to have Cura work in mm (nor any other unit of length other than mm).

I thought all countries world-wide had switched to the metric system?

 

The UK has switched gradually, with the latest units changed around the year 2000, I think? Today in the UK the old imperial units are only allowed for "drinking and driving", as one Englishman said on another forum. (=for road signs and beer bottle labels). But correct me if this info is incorrect.  :-)

 

The USA has officially adopted the metric system in 1875 (yes, 18..., not 19...), although most politicians, government officials, and press people are not aware of this. So they keep converting these metric units back to imperail units for "convenience", although it is very inconvenient for them, and it slows down conversion in everyday life. This causes big headaches for US-technicians, engineers, industry, and all other internationally oriented businesses.

 

I thought the handfull remaining countries in Africa and Asia, previous English colonies, had also switched recently, except maybe Burma/Myanmar?

 

Although in daily life people tend to keep using their old habits of course, just like we still use horse-power for cars instead of kilowatt. I guess because the number in horse-power is 1.3x higher than in kilowatt, so it sounds more impressive.  :-)

This is our culture and I raised by it. I don't ask other people to change their culture. 

 

Also there are many reasons why people may be using imperial system. For an example an existing design may be using the imperial system.  

 

I have always worked in both systems and I think all systems should support both.

When using a format like 3MF, there is no need for a conversion, since the format itself simply defines the unit (which is used by Cura to convert into mm). Some formats (like STL) don't have this, but the most commonly used unit for STL's is metric (so Cura assumes this). If it is in inches, it's also rather trivial to convert it, as it's just scaling it by 25.4.

Also allowing for settings to be in multiple systems would be a lot more difficult, and add an maintenance burden on us. This is why we chose not to support it and keep all settings in the scientific (and thus metric) system.

 

I also don't think it matters that much. Settings might say things like 50 mm/s, but usually if people change it, they change it based on what's already there (eg; It needs to be a bit faster, so let's make it 60). For these relative changes the unit doesn't have that much impact.

I think where choice of units really matter is in the design software...something I think is already the case.

Based on this thread I think I'm screwed for being in US! lol There should be an easy conversion system or plug in to fix this issue. isn't it?

You don’t create designs in Cura. All of the critical dimensions (nozzle size, layer heights, etc.) are in mm across the 3D printing community.

 

where other units matter is in design software, like Fusion 360, Freecad, or TinkerCad, to name a few.

 

Those design systems allow you to design in whatever units are best for you (though if you design in inches and enter a dimension as 15/64”, it will show as the decimal equivalent 0.234375”.

 

In that same software simply set the STL export units to mm (STL files are dimensionless).

 

And, BTW, I am also in the US, and grew up on inches & feet. But I do 99%of my designing in metric.
