This is indeed a good application of hmeasure. However...

That's not what tolerance is for - tolerance is more for recording the
possible error in a measurement (e.g. plus or minus 5%). This doesn't seem
to be used very much, which is why the current hmeasure draft mentions it
as an at-risk feature.

hMeasure also contains an optional "item" property much like the property
of the same name in hReview. It records what the measurement is actually
measuring. i.e. what is the thing that contains 15mg of Vitamin C.


<p class="hmeasure">
  <span class="item">100 mL of Orange Juice</span> contains
  <span class="num">15</span> <span class="unit">mg</span> of
  <span class="type">Vitamin C</span>.
