CBM Calculator, Meaning, CBM to KG & Shipping | Freightos

1000 kg = 1 CBM. AIR CARGO KG to CBM. Calculating CBM for air cargo is different than for ocean freight. The standard formula used is length (cm) x width (cm) x height (cm) ÷ 6000 = volumetric weight (KG)/1 CBM ≈ 166.6666 KG. Any calculation for air freight will use this conversion, so it's worth noting this rule of thumb: 167 kg = 1 CBM

Elastic and Inelastic Collisions - Purdue University

Elastic and Inelastic Collisions • Energy is not conserved in a perfectly inelastic collision. • If the objects bounce apart instead of sticking together, the collision is either elastic or partially inelastic. – An elastic collision is one in which no energy is lost. – A partially inelastic collision is one in which some energy is lost, but the objects do not stick together.
