Single Cocoon Weight MG

Calculate tare-corrected batch and pooled single-cocoon mg means with count weighting; no nominal breed cocoon mass table.

Description

A cocoon sample's container must be removed from gross mass.

A cocoon sample's container must be removed from gross mass. Pooled single-cocoon weight uses total net mass over total counted cocoons.

Calculate tare-corrected batch and pooled single-cocoon mg means with count weighting; no nominal breed cocoon mass table.

When to use Single Cocoon Weight MG

Use this tool to calculate tare-corrected batch and pooled single-cocoon mg means with count weighting; no nominal breed cocoon mass table.

Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.

How to use Single Cocoon Weight MG and understand its results

Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
Enter grossSampleMassesGrams, containerTaresGrams, cocoonCounts using the field table and calculation rules, then run the tool.
Read batchMeanCocoonMassMg, pooledMeanCocoonMassMg. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
grossSampleMassesGrams	Gross sample masses grams	list of number	Required
containerTaresGrams	Container tares grams	list of number	Required
cocoonCounts	Cocoon counts	list of number	Required

Align nonnegative gross and tare masses with positive integer counts. Reject tare above gross; return local and pooled means with count weighting.^[1]

Paired lists must be nonempty and have equal lengths.

mean mg/cocoon = 1000 × (gross grams − tare grams)/cocoon count

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
batchMeanCocoonMassMg	Batch mean cocoon mass mg	list of number
pooledMeanCocoonMassMg	Pooled mean cocoon mass mg	number

Limitations and assumptions

No breed-specific nominal weight or representative-sample guarantee is provided.

Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Shell Weight Percent SR: Compare matched shell/whole mass ratios on as-received and moisture-corrected dry bases, preserving pooled mass weighting instead of averaging individual percentages. For a complementary task, use Double Cocoon Percent Defect Rate: Audit double-cocoon count share and a caller equal-mass price-discount scenario; count share is not claimed to be measured double-cocoon mass share.
