Only one selected paint has declared volume
The Ultramarine tube is explicitly 8 ml. The set contains twelve half pans, but no verified millilitre fill quantity for those pans has been established here. Half Pan is a retail format/count description, not permission to invent a standard paint volume.
Mass is another field
Eight millilitres is not automatically eight grams. The site has no verified product-specific density and does not convert paint volume to net mass. Shipping or package weight on a retailer page is also not the paint’s net contents. A package containing a case and brush cannot be treated as pure pigment mass.
A comparison example
Two selected tubes provide sixteen declared millilitres. One selected set provides twelve assorted half pans and a brush. Neither statement supplies the missing denominator needed for a volume-equivalence comparison. The calculator shows the supported selected unit or refuses the requested conversion.
A concrete order check
If a seller lists package weight near a tube size,do not divide the ticket by that shipping weight and call the result a paint-mass rate. Packaging and accessories may be included. The selected8ml declaration supplies a legitimate volume denominator;the unverified net mass should remain blank until the maker provides it.
Use a different question
Ask whether the required purchase is a particular tube, a complete assortment or a refill format. Then compare exact matching packages on that basis. The site does not estimate pan capacity, refill instructions, painting area or cost per completed artwork.
