Adding width of text to node coordinate?

I am currently trying to position some text in the center of a square drawn in a tikzpicture, like so:
However, I am having a bit of trouble.
Take the following example:
documentclassarticle
usepackage[utf8]inputenc
usepackagegraphicx
usepackagetikzpagenodes
usepackagetikz
usepackagecalc
usepackagelayouts
begindocument
begintikzpicture[overlay, remember picture, x=1cm, y=1cm]
newcommandboxWidth5cm;
newcommandboxHeight3cm;
newcommandboxPosX5cm;
newcommandboxPosY-5cm;
newcommandsomeTextHello World;
newcommandtextPosXboxPosX + (printinunitsofcmwidthofsomeText/2);
newcommandtextPosYboxPosY + boxHeight / 2;
draw [line width=0.05cm, rounded corners=.3cm, color=red] (boxPosX,boxPosY) rectangle ++(boxWidth, boxHeight);
node at (textPosX, textPosY) someText;
endtikzpicture
enddocument
The problem arrises when I try using the width of the text: widthofsomeText/2 (from the calc package). (Reference Post)
According to the same reference post, widthof returns a length in points, which is incompatible with centimeters. Therefore, I tried converting to centimeters by using the method described here: printinunitsofcmwidthofsomeText.
However, this still yields an "Illegal unit of measure (pt inserted)."
What am I doing wrong and how can I correctly convert my units from points to centimeters?

You cannot do computations withnewcommand, usepgfmathsetmacroinstead, e.g.pgfmathsetmacrotextPosXboxPosX + width("someText")*1pt/2cm;. But this is absolutely unnecessary here, as far as I can see.

From your code I sort of sense what you might want:
documentclassarticle
usepackage[utf8]inputenc
usepackagetikzpagenodes
usepackagecalc
usepackagelayouts
begindocument
begintikzpicture[overlay, remember picture, x=1cm, y=1cm]
newcommandboxWidth5cm;
newcommandboxHeight3cm;
newcommandboxPosX5cm;
newcommandboxPosY-5cm;
newcommandsomeTextHello World;
node[draw,line width=0.05cm, rounded corners=.3cm, color=red,
minimum width=boxWidth,minimum height=boxHeight,text=black] at
(boxPosX,boxPosY) someText;
endtikzpicture
enddocument
Instead of newcommand use pgfmathsetmacro to do computations, e.g. pgfmathsetmacrotextPosXboxPosX + width("someText")*1pt/2cm;. However, I think that all the complicated computations are unnecessary here. To put a text in the center of a box, it suffices to say node[draw]text. And then you can do all sorts of spirifankerln like adding a minimum width, rounded corners etc.

Why can I do that addition in my new command fortextPosY, but I cannot do more complex computation? Why doesnewcommandallows some computation?
– Dan Hoynoski
26 mins ago
And I need something complex like this, because I will have several rectangles of the same size, each of which will have a unique string in them. The node method contours around the text only and adding redundant spaces is messy in my opinion.

@DanHoynoskinewcommandby itself does not allow for computations. You're loading thecalcpackage (which is not to be confused with the TikZ library of the same name), which allows you to do computations, but I guess once you load TikZ, this is sort of obsolete. And no, you can put pretty much anything inside a node oftikzpicture, graphics, equations... (just not tikzpictures, at least you shouldn't). There are tons of libraries which allow you to arrage rectangles of the same size, e.g.matrixorchains.

you are absolutely correct! Using a node is so much better. And that is strange, because if you settextPosXtoboxPosXin my original code above (to prevent that conversion error) and then it compiles just fine even withboxPosY + boxHeight / 2being there. Are you say that because I am loading the calc package, it added this ability tonewcommand?

@DanHoynoski No, calc does not do any magic of that kind. It is TikZ which starts to parse these things and then sees "Oh, here is somex+y, let's add them." You can always check such things by saying e.g.typeoutboxPosXand the you will see whether this is the stringx+yor the sum.

If the text is to be placed in the centre of the rectangle, simply place it with a node midway down the path.
draw [line width=0.05cm, rounded corners=.3cm, color=red]
(boxPosX,boxPosY) rectangle ++(boxWidth, boxHeight)node[midway,text=black]someText;

@DanHoynoski No, calc does not do any magic of that kind. It is TikZ which starts to parse these things and then sees "Oh, here is some

If the text is to be placed in the centre of the rectangle, simply place it with a node midway down the path.
draw [line width=0.05cm, rounded corners=.3cm, color=red]
(boxPosX,boxPosY) rectangle ++(boxWidth, boxHeight)node[midway,text=black]someText;

I appreciate your answer! I did not think about adding another node like this! If I could accept two answers, I would!

You cannot do computations with
newcommand, usepgfmathsetmacroinstead, e.g.pgfmathsetmacrotextPosXboxPosX + width("someText")*1pt/2cm;. But this is absolutely unnecessary here, as far as I can see.– marmot
