The default batch size on the Formulations page is 1,000 grams. Each time you come to this page or select a different color the formulation data will be calculated for a batch of 1,0000 grams.

You can click one of the quick-select batch size buttons to change the formulation to one of several preset batch size values.
If you need a batch size other than those available as quick-selects, enter that batch size (in grams) in the custom edit box and click the Custom button.
The New Batch Size button opens the Batch Calculator page.
