One focused task

From a question to a clearer record.

Start with the exact inputs

For a percentage explicitly defined as mass per volume, the number represents grams per 100 mL. Multiply by ten to express milligrams per mL. Check the original labeling convention first.

Review a concrete example

An illustrative 0.9% mass-per-volume statement corresponds arithmetically to 0.9 g per 100 mL and 9 mg per mL.

Keep the boundary visible

This is not a mixing recipe, dilution instruction, medical dose or confirmation that different products can be substituted.

Useful without a purchase
