Yup, 34,83 cm seems about right. I did an investigation previously on this list and reached the same conclusion:

Sadly, we know very little of units of length smaller than one 'uj, but yes, there is confirmation of those measurements being expressed using decimals. In the link above, you'll find examples such as
