There should be a help file entry on that, but only for M14 and beyond, I think.

I just define a unit at the beginning, so km=1000*m for instance, and then use km as a unit.

I work in Oil & Gas and pretty much every sheet I've ever built has a hidden area at the top where MCF:=1000*ft^3, MMCF:=1000 MCF, bbl:=42*gal, etc.  I also have the ideal gas constent, MW of air, and the equation for density in that area since I need that informaiton so often.

That standard hidden area is in a "white board" sheet that I open whenever I want to just do some quick thing that I plan to throw away.  If I'm starting something that I might want to keep, I open the whiteboard and rename it.

I tried to define the units (I think it was V13) using the published procedure, but it didn't seem to be worth it.

I was just looking at a worksheet and wanted to change the unit system, I noticed a "Display" tab (go to "Tools", "Worksheet Options" and pick "Display).  DKK is an option under Currency.  I'm not sure how MathCad uses its "Currency" variable, but it must use it somewhere.

David, Mathcad simply (?) treats the currency values as being independent of the other units (e.g. see Buckingham's Pi Theorem on Wikipedia), so that you can't express pay (in dollars / hour) in another unit scale (say furlongs / fortnight).

If you do it will re-insert a correcting term of (dollars / furlong), which is currency per length.

If only they would add the Angle unit, and a 'User unit', so that we could have torque in N.m/rad, distinct from Work in N.m, and I could distinguish Input referred voltages from Output referred voltages...  

I use Mathcad 13 with no built in currency. If I want a dollar unit, I just set dollar:=1, and insert the unit where it is needed in a result.
