Adult consumer arithmetic—not a dose, treatment recommendation, legal determination, laboratory result, or proof that a product is safe, accurately labeled, or suitable for any person. Use the exact regulated package and current official source. If a child may have been exposed in the U.S., call Poison Control at 1-800-222-1222; call 911 for an immediate life threat.
THE USEFUL PART
Keep these in your head.
- A serving and a piece are not automatically the same. Record the label's serving amount, servings per package, and actual unit count before calculating.
- Calculated package total equals the labeled amount per serving multiplied by labeled servings. Per-unit math requires a real unit count and assumes even distribution only for arithmetic.
- A mismatch is a question to resolve with the licensed seller, producer, current regulator, and exact-lot evidence—not permission to relabel or guess.
- The selected-piece result is multiplication, not advice about how much to consume. Delayed effects and individual variability remain outside the calculator.
Run the package arithmetic
Enter the printed serving fields and package unit count. Blank values stay unknown rather than becoming a recommendation.
Nothing is uploaded or saved. Per-unit results assume the labeled package total is evenly distributed across the entered units; real products and divided pieces may vary.
Translate the four label objects
| Field | What to copy | Do not substitute |
|---|---|---|
| Per serving | Milligrams of THC, CBD, or another named cannabinoid for the label-defined serving. | Package total, percentage, laboratory concentration, or a remembered amount. |
| Serving size | The label's number of pieces, mass, volume, or other measure that defines one serving. | One piece merely because the product is divided. |
| Servings per package | The printed count of label-defined servings in the whole package. | Piece count unless the label explicitly makes them equal. |
| Package total | The printed total milligrams for the entire package. | A per-serving value copied into the total field. |
| Piece or unit count | The actual count of gummies, chocolates, capsules, lozenges, or other discrete units. | A guessed count for a liquid, powder, or unevenly divided product. |
For a label that says 5 mg THC per serving, two pieces per serving, and five servings per package, the cross-check is 25 mg THC per package and 2.5 mg per piece. That does not establish that pieces are perfectly uniform, that the printed amount is accurate, or that any amount is appropriate for a person.
Treat a mismatch as an evidence problem
- Re-read the basis.
Confirm cannabinoid, serving size, servings, piece count, decimal point, units, and whether the product is a liquid or divisible solid.
- Preserve the package.
Photograph the complete label, product name, producer, lot or batch, dates, warnings, receipt, and QR destination without changing the contents.
- Match the exact lot.
Use the regulator or producer route to find the final certificate or required testing record. A different flavor, size, lot, or revision is not a substitute.
- Ask before using.
Contact the licensed seller or producer for a documented explanation. Do not average conflicting numbers, rewrite the label, or use a search snippet as the controlling record.
- Escalate the right problem.
Use the current state regulator for a regulated-product label concern, the appropriate health route for symptoms, and Poison Control for a possible exposure.
Keep arithmetic outside the safety gate
- NO DOSE OUTPUTThe calculator never recommends an amount or decides who should use cannabis.
- NO TIMING CLOCKCDC says eating or drinking cannabis can take longer to have an effect and may increase the chance of consuming too much. A result cannot tell when effects begin or end.
- NO QUALITY SCORELower milligrams, higher milligrams, or a matching total cannot rank ingredients, contaminants, consistency, freshness, legality, or value.
- NO LAB CONVERSIONPercent, mg/g, mg/mL, dry-weight values, uncertainty, LOD, and LOQ need their own basis. Do not paste them into per-serving fields.
- NO ERROR TOLERANCE VERDICTJurisdictions and product programs set their own rules. A percentage difference is not a compliance conclusion.
Use the result in a complete checkout
- Verify the licensed or otherwise lawful source for the exact jurisdiction and product type.
- Match product name, form, size, producer, lot or batch, dates, and package condition.
- Read active ingredients, ordinary ingredients, major allergens, warnings, directions, and storage.
- Reconcile per-serving, serving-size, servings-per-package, unit count, and package-total arithmetic.
- Match the exact lot to its available certificate or official record and check current recalls.
- Keep the original package functional, reclose it, and place it in locked household storage.
- Know the seller return, regulator complaint, Poison Control, and emergency routes before opening.
