THE BASIN & PALM SUPPLY INDEX
Units and refills

Can I compare a cream ounce with a handwash fluid ounce?
Similar written numbers can describe different physical quantities.

Does a34-fluid-ounce refill fill a12-fluid-ounce pump three times?
Approximate marketing wording is not three guaranteed full bottle fills.

Will a gel refill work in any foaming soap dispenser?
Format and dispenser instructions matter more than a shared scent.

Can the bottle volume tell me the exact cost per handwash?
A nominal bottle volume does not establish pump output or use count.
