Key takeaways
- Record the units and source of the stated factor.
- A simple volume estimate is not a complete stowage plan.
Test the space requirement
ILLUSTRATIVE — invented teaching inputs. Assume cargo of 10,000 tonnes and a stowage factor of 1.4 cubic metres per tonne. Estimated space = 10,000 × 1.4 = 14,000 cubic metres, before practical allowances.
The example excludes practical stowage allowances and vessel-specific constraints. Obtain cargo information and the relevant usable hold capacity before treating a vessel as suitable.
- Confirm whether the supplied factor is in cubic metres per tonne or another unit.
- Apply the factor to the proposed quantity consistently.
- Refer the result and cargo characteristics for technical suitability review.
For a light bulk cargo, a vessel can encounter a volume limitation before reaching its weight allowance. That is why a cargo enquiry should carry more than a tonnage figure.
Common mistakes
Avoid using a generic cargo label as proof of an exact stowage factor. Do not mix cubic feet and cubic metres. Do not present a mathematical space estimate as confirmation that loading can proceed safely.

Frequently asked questions
Does a higher factor mean more space per tonne?
Yes, when comparing factors expressed in the same units.
Is stowage factor identical for every parcel?
Do not assume so; request information for the actual cargo.
Does enough deadweight prove enough hold space?
No. Weight and volume are separate constraints.
What belongs beside a stowage-factor figure?
Its units, cargo description, source and any qualifications affecting its use.
