Default Standard Errors for Levelling

    Is there a good reason My Default Standard errors for Levelling have been changed to inchs?  And is there any way to fix it?

    Have you used the same template as before?

    Check in Units->Distance that the whole project is set to Metre.

    Same template. Same units, but for some reason the 0.028 ft has changed to 0.028 in.

    The whole point of my first post, which I now see that I didn't mention, as that this happened immediately after my update to version 5.60.

    Which version have you been using before? I couldn't reproduce that in any version from 5.20-5.6 that I have installed.
    In the end is inch in my opinion the correct unit anyway. A modern digital level has usually a km error for a double levelling of around 0.3 mm/km, 0.019 inch/mile.

    My previous version was, I believe, 5.50.

    Is inch the correct unit?  That I really didn't think to check.  I just know that for years it has been 0.028 ft/km of levelling out of the box. It could be possible that this is a fix a LONG time in coming.

    I'll have to check into that.

    I had this same question. The units are not labled on the dialogue where we specify the leveling standard errors. I changed units to meters and confirmed it is 0.7mm/km which is correct, but when I switch back to USFT, I see 0.028 which is NOT 0.7mm so I'm wondering if that is inches/mile?

    Every unit converter will tell you that 0.7 mm is 0.028 inches. The question is if it is really applied per km or miles.
    5.60.2 shows on my computer the unit correct as inch and says it is per km.
