Non-standard units of measurement are a major cause of misunderstandings in business transactions. Terms such as "roll," "bundle," "pack," or "bag" may have different meanings depending on the manufacturer or seller, leading to disputes, financial losses, and customer dissatisfaction. To avoid these problems, buyers and sellers should always agree on standardized units and clearly define product quantities.
In business, words matter. Non-standard units of measurement is among. A single ambiguous word can determine whether a transaction ends in satisfaction or in court.

Every day, buyers and sellers negotiate prices based on the quantity of goods being exchanged. When those quantities are described using unclear or non-standard units of measurement, misunderstandings become almost inevitable.
One common mistake is the use of expressions such as roll, bundle, pack, heap, bag, carton, basket, basin, or truckload without clearly defining what each term represents. While these expressions may be familiar within a particular company or locality, they often have no universally accepted meaning.
The result is confusion, financial loss, damaged business relationships, and sometimes costly legal battles.
The Exercise Book Dispute
Consider an interesting example. A school entered into an agreement with a printer to supply 10 rolls of exercise books. Payment was made in full before delivery. When the books arrived, the school discovered that only 50 exercise books had been supplied.
The printer insisted that there was no mistake because, according to his company's internal practice, one roll equals five exercise books.
The school believed that a "roll" represented a much larger quantity and sued the printer.
Surprisingly, the school reportedly lost the case because the agreement never defined what a "roll" meant. Since there was no recognized legal or industry standard establishing the quantity represented by a "roll" of exercise books, the court relied on the wording of the agreement and the available evidence.
Whether this exact story occurred as narrated or has been shared as an educational illustration, it highlights an important legal and commercial lesson: when a quantity is not clearly defined in a contract, disputes become much harder to resolve.
What Makes a Unit of Measurement Standard?
A standard unit is one that has been officially recognized and accepted so that everyone understands exactly what it means. Non-standard units of measurement is the direct opposite.
Examples include:
- Kilogram (kg)
- Gram (g) - Litre (L)
- Millilitre (mL)
- Metre (m)
- Centimetre (cm)
- Piece
- Dozen (12)
- Score (20)
- Gross (144)
These measurements have accepted definitions and are recognized internationally or within legal trade systems.
When someone orders:
- 100 pieces
- 50 kilograms
- 20 litres
- 500 metres
there is very little room for misunderstanding.
Why "Roll" Is Not a Standard Quantity
Many people wrongly assume that "roll" represents a fixed number. It does not.
Unlike:
- Pair = 2
- Dozen = 12
- Score = 20
- Gross = 144
the word roll merely describes the way something is wound or packaged.
Examples include:
- Roll of tissue paper
- Roll of fabric
- Roll of cable
- Roll of roofing sheet
- Roll of wallpaper
- Roll of film
Each manufacturer determines the length, weight or quantity contained in a roll.
Therefore, one company's roll may contain:
- 5 pieces
- 10 pieces
- 20 pieces
- 50 metres
- 100 metres
Another company's roll may contain an entirely different quantity. There is simply no universal standard.
Why Non-Standard Units of Measurement Cause Business Disputes
Businesses frequently use expressions that mean different things in different places.
Examples include:
- Bundle
- Pack
- Heap
- Sack
- Bag
- Basket1
- Basin
- Wrap
- Bale
- Tin
- Bottle
- Cup
- Carton
- Crate
- Trailer load
- Pickup load
- Wheelbarrow load
Without specifying dimensions or quantities, these words can easily be interpreted differently by different people.
The Legal Implications
Contracts depend on certainty. One of the first questions a court considers is:
"What exactly did both parties agree to?"

If the agreement contains vague expressions that neither party defined, proving your interpretation becomes difficult.
Courts generally interpret contracts based on:
- The exact wording.
- Industry practice.
- Evidence presented.
- Previous dealings between the parties.
- Applicable laws and regulations.
Where ambiguity exists, both parties may bear responsibility for failing to define important terms.
Consumer Protection and Fair Trade
Standardized measurements protect everyone.
They protect:
- Consumers
- Manufacturers
- Retailers
- Wholesalers
- Government agencies
- Exporters
- Importers
Accurate measurements ensure that buyers receive what they paid for while sellers avoid unnecessary disputes.
Why Small Businesses Should Learn This Lesson Many small business owners focus mainly on pricing. Far fewer pay attention to how quantities are described.
Instead of writing:
- One roll
- One pack
- One bundle
they should write:
- 50 exercise books
- 12 notebooks per pack
- 100 metres of cable
- 24 bottles per carton
- 500 sheets per ream
The clearer the description, the lower the chance of disagreement.
Best Practices for Every Business
To avoid costly misunderstandings:
1. Always specify the exact quantity.
2. Use internationally recognized units where possible.
3. Clearly define any special packaging terms.
4. Include quantities in invoices.
5. Include quantities in receipts.
6. Include quantities in contracts.
7. Avoid assumptions.
8. Ask questions before making payment.
9. Keep written records.
10. Ensure both parties understand the same thing.
Lessons for Buyers
Before paying for goods:
- Ask exactly how many pieces are included.
- Request written confirmation.
- Verify packaging.
- Read contracts carefully.
- Avoid relying on verbal explanations.

Lessons for Sellers
Honest businesses also benefit from clarity.
Specify:
- Quantity
- Weight
- Volume
- Length
- Packaging
This builds customer confidence, reduces complaints and strengthens your reputation.
The Role of Regulatory Authorities
Weights and measures laws exist to promote fairness in commerce. Regulatory agencies in many countries require traders to use approved measuring instruments and standardized units when selling goods by weight, volume or length. Clear labeling and accurate descriptions also help protect consumers and promote confidence in the marketplace.
Conclusion
Business thrives on trust, and trust thrives on clarity. Words like roll, bundle, pack and similar expressions may sound harmless, but when they are not clearly defined, they can become expensive sources of conflict.
Whether you are buying exercise books, printing materials, food items, construction materials or industrial supplies, insist on quantities that leave no room for doubt. Remember:
- A dozen is always twelve.
- A score is always twenty.
- A gross is always one hundred and forty-four.
