Rounding (Weight)
Carriers round weights up to standard increments for billing.
Definition
Weight rounding is a billing practice where carriers round the chargeable weight up to the next specified increment. Common rounding increments are 0.5 kg, 1 kg, or 0.1 kg. For example, if your chargeable weight is 5.3 kg and the carrier rounds to 0.5 kg, you'll be billed for 5.5 kg. Rounding can be applied per piece or to the total shipment weight, depending on the carrier's rules.
Why It Matters
Rounding can significantly impact costs, especially for multi-piece shipments. If each piece is rounded individually (per-row rounding), you may pay more than if rounding is applied to the total. Understanding your carrier's rounding rules helps you estimate costs accurately.
Example
You ship 5 pieces, each with a chargeable weight of 2.2 kg. With per-piece rounding to 0.5 kg, each becomes 2.5 kg = 12.5 kg total. With total-only rounding, the sum is 11 kg, rounded to 11 kg—a difference of 1.5 kg.
