That must have been it. I was wondering if it might have been due to exceeding linel (I use a wide terminal window), but the manual says that backslashes in that case would be used only for broken atoms (i.e. symbols/numbers/strings).

I’ll take a look at that, thanks.

Thanks for the background behind the two packages.

Thank you for the ezunits package; it came much closer to how I conceived a units package might work, i.e. something like how Frink handles units.
Could the ezunits database be extended somehow to separate (most) SI prefixes from SI units, and combine them as needed? For example, having “kilo-” and “k-” prefixes with a value of 1000, so that “kilometer” would be parsed as a combination of “kilo-” and “meter”, and “km” as a combination of “k-” and “m”, rather than requiring separate database entries for every combination of SI prefix and SI unit? (“kilogram” and “kg” would be the exceptions to retain separate entries, since the kilogram is a SI bsse unit.)
An analogous prefix for US customary units could be “survey-” with a value of 500000/499999 for units of length.

Yes, indeed it does, thank you.
