Remembering a chum recipe as percentages and converting it to weights on the boat is a chore. Enter the dry total in pounds or ounces and each ingredient's share, and this page gives the weight of every ingredient, the water to add and the weight of the finished wet mix.
The arithmetic is simple proportional splitting: the dry total times each share. Results are shown in your chosen U.S. unit with the metric equivalent in parentheses, using the exact definition 1 oz = 28.349523125 g (1 lb = 16 oz = 453.59237 g). Water is added separately as a share of the dry total. The share total is compared against 100% at the same two decimals shown on screen, so the number you see and the message you read never disagree. When the total is not 100%, no result appears and the current total is reported instead. Current as of October 2026.
No recommended share is offered for any ingredient. Mixes depend on the product, the target species and the current, and no official standard exists. Performance, consistency and spread are not covered either. The sample numbers in the fields show the input format only; take your actual shares from the product you use and your own experience.
Frequently Asked Questions
No. Mix ratios depend on the product, the target species and the current, and no official standard exists. The sample numbers in the fields only show the input format.
No result appears and a message reports the current total. Splitting weights from a total that does not add up would not match your dry weight, so the calculation runs only when the total, rounded to two decimals, is exactly 100%.
Performance is not covered. This page only splits the weight by the shares you entered and adds the water amount. Judge consistency and spread on the water yourself.
