SF Express uses a divisor of 6000 cm³/kg (metric) — this carrier publishes only metric divisors. The DIM weight formula is volume divided by this number, rounded up to the nearest whole pound or kilogram.
SF Express applies dimensional weight to packages above No minimum. The billable weight is always the greater of the actual weight or the calculated DIM weight.
Use right-sized packaging — every cubic inch you save is divided by the divisor and removed from your billable weight. Avoid excessive void fill and consider custom box sizes for products you ship frequently. For occasional shippers, use the calculator above to test packaging changes before you commit to new materials.
