Yes. It's not intuitive that registers defined using any other units are stored in basic units, and that groff must be explicitly told this whenever such values are referenced. $ cat testfile .nr a 4i .tm \n[a] $ groff testfile 288000 The usual way to use such a register is to place a "u" after it, so that groff interprets its value as being in basic units. For example, to put four inches of horizontal space on the page: .nr a 4i far\h'\n[a]u'apart This separates the words "far" and "apart" by four inches. If you omit the "u", \h would insert 288,000 ems (its default unit) of horizontal space, which would require a serious horizontal scrollbar on your PostScript/PDF viewer.
