How this service works
Cargo density in kg/m3 and lb/ft3, stowage factor, and whether air (1:6000) or sea freight bills on weight or volume.
Output
Returns cargo density in kg/m³ and lb/ft³, cubic metres (CBM), cubic feet, stowage factor in m³ per tonne, air chargeable kg, sea chargeable revenue tons, and a verdict on whether air freight and sea freight each bill on actual weight or volumetric weight, plus a human-readable summary.
Example use cases
Air freight billing classification
“I'm shipping electronics that weigh 200 kg and the carton dimensions are 90 cm long, 60 cm wide, and 50 cm tall. Can you work out the cargo density and tell me whether my air freight carrier will bill me on the actual weight or the volumetric weight under the 1:6000 rule?”
Sea freight stowage factor check
“Our cargo is 1,200 kg gross weight and measures 150 cm x 100 cm x 80 cm. What's the stowage factor in m³ per tonne, and will the sea freight be billed on weight or volume?”
Dense machinery shipment density check
“We're shipping heavy machinery at 3,500 kg with dimensions 200 cm long, 120 cm wide, and 110 cm tall — what's the density in kg/m³ and lb/ft³, and how does it bill for both air and sea freight?”
Technical details
Endpoint
GEThttps://shipping-calc.x402tookit.com/freight-density?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine freight density and classify whether a specific cargo shipment will be billed on gross weight or volumetric weight for air or sea transport — especially when preparing freight quotes, comparing shipping modes, or checking whether a shipment is 'light' (volume-rated) or 'heavy' (weight-rated). Prefer this over dimensional weight endpoints when you need density-specific metrics like kg/m³, lb/ft³, and stowage factor rather than just chargeable weight.
Side effects
- Missing required query parameters (weightKg, length, width, height) returns an error
- Zero or negative dimensions/weight produce invalid results
- Unsupported unit value (not cm, in, or m) may cause incorrect calculation
- Network timeout or service unavailability returns no response
