\u3010TL;DR Executive Direct Answer\u3011<\/strong><\/p>\n

A 5 cubic foot (\u2248141.6 liter) volume holds roughly 7\u2013140 kg depending on bulk density of the contents \u2014 water-equivalent mass is 141.6 kg at 1,000 kg\/m\u00b3, while typical corrugated-packed goods at 50\u201380 kg\/m\u00b3 land at 7\u201311 kg. Safe payload must be derated for containerboard ECT stacking limits and ocean-transit moisture absorption, not raw volume.<\/p>\n<\/div>\n

1. The Volume-to-Mass Conversion: Physics, Not Guesswork<\/h2>\n

Cubic feet is a volumetric unit; kilograms is a mass unit. No single universal conversion exists \u2014 the bridge between them is bulk density (kg\/m\u00b3)<\/strong>. The governing equation for any packaged-goods payload estimate is:<\/p>\n

m (kg) = V (m\u00b3) \u00d7 \u03c1 (kg\/m\u00b3) \u00d7 fill efficiency \u03b7<\/strong><\/p>\n

Where 5 ft\u00b3 = 0.14158 m\u00b3. Fill efficiency \u03b7 for irregular or void-filled shipments typically runs 0.55\u20130.85; rigid molded inserts approach 0.90+. The hypothetical worked examples below illustrate the spread (assume \u03b7 = 0.80 unless noted):<\/p>\n
