The problem: recalculating units by hand before every mix

Formulators often design by weight while the lab mixes by volume. Converting each ingredient by hand is slow and easy to get wrong.

The formulator designs in grams, but the lab doses liquids by volume. Each trial needs every ingredient converted using its specific gravity, and a slip changes the formula.

What this demo shows

  1. Enter three primer trials by weight.
  2. Switch all three trials from grams to milliliters from one menu.
  3. Keep one pigment in grams where that suits the lab.

Why it matters

Converting units by hand is a common source of mixing errors. Switching the basis from one menu, using each ingredient's specific gravity, removes that risk.

Keeping some ingredients in grams, such as pigment, fits how the lab actually works, and the formula stays one record either way.

Read the transcript

Uncountable keeps your R&D formulas as structured data. These three primer trials are entered by weight in grams. Set basis switches all three trials to volume at once. Every ingredient switches to milliliters, converted with its own specific gravity. Still weigh the pigment? Set it back to grams in trial three. Weight or volume, it is one formula in Uncountable.

FAQs

Can I switch a formula from weight to volume?

Yes. Set basis switches all selected trials from grams to milliliters at once.

How are milliliters calculated?

Each ingredient is converted using its own specific gravity.

Can some ingredients stay in grams?

Yes. In the demo, the pigment is set back to grams in one trial while the rest is mixed by volume. It stays one formula either way.
