I was doing some research for my sister's use of vitamin B12 supplements
and came to this page:
http://www.webmd.com/diet/vitamin-b12-15239?page=2
It contains a small chart:
Vitamin B12Normal:
More than 200-835 picograms per milliliter (pg/mL)
148-616 picomoles per liter (pmol/L) (SI units)
Interestingly, WebMD apparently considers picomoles per liter to be in
SI units but picograms per milliliter not to be in SI units.
Of course, the non-SI unit is the liter (or milliliter) but that's
acceptable for use with the SI. So, in my mind neither value statement
is "more SI" than the other.
How do you view this, Paul Trusten?
