A quick decision brief for this specific tool
Inputs that matter
One de-identified completed batch record; record type, batch/revision, raw-material identity, weighed-output identity and one-batch applicability; source-owned as-received, dry-mass or other explicitly defined shared basis; independently selected mg/g/kg/oz/lb input and output masses; input/output measurement and tare records; completion timestamp and process-record source; reviewer role, review timestamp and retention record; completed-mass-ratio, source-owned-identity, same-basis and nondecision boundaries; plus an optional all-or-none independent same-basis yield percentage and source
Output to expect
Input and output masses normalized to grams, dimensionless output/input mass ratio, completed yield percentage, g/kg input and mg/g input, output-minus-input audit value, above-input audit prompt, and optional calculated-minus-independent signed percentage-point difference without a pass/fail result
How it works
Validate the complete record and four refusal boundaries; normalize each positive recorded mass with exact SI or defined avoirdupois factors; divide output mass by input mass; express the same ratio as percent and g/kg; require independent percentage and source together; calculate only a signed same-basis difference; preserve six nondecisions and a versioned Project output; never insert moisture, solvent, tare, loss, sampling, calibration or uncertainty corrections
Confirm the exact batch/revision, material, plant part/condition, weighed-output definition, completion time, mass basis, scale/tare method and source revision. Another batch, material, output definition, wet/dry basis, process stage or source revision needs another record.
If comparing an independent result, confirm it uses the same numerator/output definition, denominator/input boundary, mass basis, batch and precision. Equality or a small signed difference is arithmetic/transcription evidence only—not measurement validity, repeatability, quality or acceptance.
Use the result only for one completed source-owned mass ratio. It does not select or optimize extraction method, solvent, temperature, time, pressure or equipment; infer expected/typical/acceptable yield; verify botanical/output identity, purity, composition or quality; correct moisture, residue, tare or losses; decide safety, compliance, release, pricing, scale-up, formulation or use; or authorize process work.
Choose your path
Built around the job you need to finish
Reproduce one completed source-owned output-to-input mass ratio across independent mass units, optionally compare one independent same-basis percentage, and refuse every benchmark, process, identity, quality, safety, compliance, release and use decision.
Fragrance-production record technician reconciling one completed batch
Convert recorded input and weighed-output masses without losing the batch, mass basis, tare/measurement or output-definition evidence.
Identify one completed de-identified batch, copy both source-owned identities and measurement records, select each mass unit and the shared basis, calculate and retain the reviewed snapshot.
Can reproduce percent and g/kg arithmetic while process settings, losses, quality, acceptance, release and scale-up remain with accountable external records.
Quality reviewer comparing a second same-basis calculation
Reconcile an independently reported yield against one transparent completed-record ratio without turning a small difference into conformance or acceptance.
Freeze the exact numerator, denominator, batch and basis, enter the optional percentage/source pair, then inspect the signed percentage-point difference and retained provenance.
Sees reproducible arithmetic and an audit prompt while identity, calibration, uncertainty, repeatability, specification and disposition stay external.
Show how unit normalization and denominator choice affect a reported percentage without presenting a training example as a typical yield or extraction recipe.
Load the de-identified example, exercise mg/g/kg/oz/lb pairs, shared-basis choices, partial optional evidence and above-input audit state, then review all Decision Boundaries.
Learners can reproduce the ratio, distinguish source identity from arithmetic and explain why process, solvent, quality and safety decisions need separate evidence.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Identify one de-identified batch/revision, the exact source-owned raw-material identity and the exact weighed-output identity. The Tool does not decide whether an output is an absolute, verify botanical identity or combine different batches.
Normalize two masses on one stated basis
Convert independently selected mg, g, kg, oz or lb values to grams, then divide output mass by input mass. Both measurements must share the same source-documented as-received, dry-mass or other explicit basis; no moisture, solvent, tare or loss correction is invented.
Express and reconcile arithmetic without a verdict
Express the same ratio as a fraction, percent, g/kg input and mg/g input. An optional independent same-basis percentage produces only a signed calculated-minus-independent difference, never a specification, quality or acceptance result.

Example Scenarios
A record technician preserves batch, input, weighed output, shared basis, scale/tare references, completion time and process-record source while reproducing the final ratio.
A reviewer compares one independently reported percentage only after confirming the same batch, numerator, denominator, mass basis and precision, then retains the signed arithmetic difference.
An instructor demonstrates unit normalization, denominator ownership and above-input audit prompts without publishing a typical yield, extraction recipe or product recommendation.
Common Mistakes to Avoid
✕
Mixing wet, dry or differently defined masses
✓
Use one source-documented basis for both numerator and denominator. If the source changes moisture, residual-solvent, tare or process-stage treatment, create a separate record rather than inventing a correction.
✕
Treating the percentage as a benchmark or release decision
✓
The result describes one completed record only. Expected yield, identity, purity, quality, repeatability, safety, compliance, pricing, scale-up and release require their own accountable evidence and review.
FAQ
It is the recorded weighed-output mass divided by the recorded input mass, multiplied by 100, for the exact batch and shared mass basis entered. It is not automatically purity, recovery efficiency or commercially acceptable yield.
A ratio is interpretable only when its numerator and denominator boundaries are explicit. ISO and IFRA terminology can organize source records, but this Tool does not independently classify or verify the entered identities.
Yes. Each mass is normalized independently using the selected unit. Their physical mass basis must still match; unit conversion cannot reconcile wet versus dry mass or different process stages.
It proves only the signed arithmetic difference between this calculation and one supplied same-basis percentage. It does not validate a scale, method, uncertainty, repeatability, specification or disposition.
This Tool is a source-preserving completed-batch mass-ratio record. It converts two recorded masses, shows the output/input ratio in several equivalent forms and optionally compares one independent same-basis percentage. It never supplies an extraction process, expected yield or approval.
