I'm afraid that Karl is right about all of the variants in these kitchen measurements. This has been my objection since the very start.

It is especially bad when one considers the fact that different forms of the same compound such as powder and crystal vary by 20% in weight when measured by volume.

This can be a calamity with developers but not very harmful with fixers unless one does not test for hypo and silver retention to get the right archival wash conditions.

Then, it beomes a calamity again!
