Loads/Units shown on drawings 3

[EngDM]

How particular are you guys with the proper capitalization of units on drawings? Personally I prefer that everything is shown with the correct letter case, especially when it comes to the units that are named after someone I.E. Newtons or Pascals, but often time I am reviewing drawings and everything is uppercase. So you get stuff in the general notes for a distance such as MM for millimeters, or KN/M.

I know it is unlikely that any errors are actually made from this, since the units are so standardized, but in a case where MPa is shown as mPa, it technically makes a massive difference.

And then an unfortunate percentage will use this "ambiguity" as an opportunity to "think it was something else" and then charge the owner an extra and blame you for it.

That's never happened on one of my projects in nearly 38 years of practice. I had one plan checker (DSA in CA) insist and I did so to get the plans approved. I had another plan checker at a local municipality. He dropped it after I pushed back.
Just how can this be misinterpreted?

@EngDM, I mentioned in an earlier comment, but newtons and pascals (as units) are always spelt in lower case

Just because it requires experience, doesn't mean some of these cowboy contractors are going to have it. The last thing I need is different ways to interpret my drawings due to omission of abbreviations.

I'm sorry that I haven't been making myself clear. Which sort of highlights my point.

Interpretation is everything and not matter how meticulous you are you can't rule out other people mis-interpreting drawings. There are ALWAYS different ways to interpret drawings.

You have some interpreted my comments as making the assumption that I'm against clarity, abbreviations or legends in drawings. Far from it. But none of that removes the requirement that those reading have the skills and knowledge to interpret them. As I've said repeatedly in the example previously, 2x10 means is completely open to interpretation.

Yea I saw that and I appreciate the correction so I can use this going forward. Thing is, I haven't used either of those words since then? Are you confusing the new way the forum shows the original post always at the top, regardless of what comment page you are on, with new comments?

I can no longer edit that post just an FYI.

The following may be of interest:
Only one style of charter should be used generally throughout at drawing. ...Upper-case letters should be used. Lower-case letters shall be used for conventional signs and symbols normally requiring such characters, e.g. mm, kg, kPa.

Ex: AS 1100.101 Cl 4.1.5.

I'm afraid that I'm one who insists on a space between the value and the unit. I would use a non-breaking space when the program may re-flow the text.

Most of the world should follow BIPM SI Brochure 9th Edition (2019) clause 5.4.3, which can be found here : https://www.bipm.org/en/publications/si-brochure

The US should follow NIST SP-330 (2019) clause 5.4.3, which can be found here : https://doi.org/10.6028/NIST.SP.330-2019

I always want to have the units in the proper capitalization, in my report and also on my drawings.
