Weight is not volume
An ounce on a weighing scale is not a fluid ounce on a bottle. To convert millilitres to grams you need the exact paint’s density in grams per millilitre: mass = volume × density. Do not assume paint has the density of water. A scale’s fluid-ounce mode may assume water or another preset liquid and be unsuitable for paint.
Tare the empty mixing cup before weighing. Follow the manufacturer’s ratio and its stated basis, especially for two-part coatings. A volume ratio cannot automatically be used as a weight ratio. See choosing a hobby paint set for application differences.
