Truffle center rolling inventory calculator

Calculate whole centers and coating requirement with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use whole centers and coating requirement to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Whole centers (count)

floor(batch kg×1000×(1−loss)/center grams).

Coating requirement (kg)

Whole center count×coating grams/1000.

Unused center mass (grams)

Usable mass−whole centers×center mass.

Symbols and units
a
Center batch mass (kg)
b
Center loss fraction
c
Target center mass (grams)
d
Coating per center (grams)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Whole centers from usable center mass; coating per center is a user-measured input. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. All numeric values must be finite. Lists contain at most 100 records; required lists must be nonempty. Rates, probabilities and fractions are entered as fractions, not percentages; fractions must be between 0 and 1. Use a single consistent user-selected currency for all amounts; no exchange-rate conversion.
