nH unit not always there in Prime 2.0

[vroberts]

Last week I had mentioned in another discussion that nH was strangely missing from the list of Units in Prime 2.0. I was told it was in Prime 2,.0 and indeed it was when I looked for it at that time. However, today it is gone again. I've attached a screen shot with the Units menu showing, and nH is not on the list. Why is nH there sometimes and not others? My system is Windows 7 Pro x64.

Sorry - It is not a built-in but an users unit.

You can/must definite it:

Thanks. I looked back at the other discussion, and I see that I asked about nF instead of nH by mistake.

It is/was an old good idea for Mathcad.

To have only base units - m, kg, s, T, N, H etc

and all prefixes for its - m, c, d, n, M, G etc

But...

m and mm is OK

in and min - ???

lb and mlb - ???

You welcome.

But!

"Thanks" is good but "Correct answer" (and thanks) is better

I knew how to define nH. The discussion was about why it seemed to be there one day and gone the next. But, you do deserve the "Correct Answer" so it has been awarded
