    For example, a box of clothing shipped internationally which weighs 10 pounds and measures 18 × 18 × 18 inches would be charged as if it weighed 36 pounds: (18 x 18 x 18)/166 = 35.1 pounds which is then rounded up to 36 pounds for shipping cost purposes.

    en.wikipedia.org/wiki/Freight_rate

    Many shipping services, especially air carriers, use dimensional weight for calculating the price, which takes into account both weight and volume of the cargo. For example, bulk coal long-distance rates in America are approximately 1 cent/ton-mile. [2] So a 100 car train, each carrying 100 tons, over a distance of 1000 miles, would cost $100,000.

    The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS. The current version, WGS 84 , defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum , and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).

    On 7 January 2024 move to IGS20 happened, so WGS 84 is now aligned with ITRF2020, including PSD (post-seismic deformation), also called G2296. On the other hand GLONASS is using PZ-90.11, which is close to ITRF2008 at epoch 2011.0 and is using 2010.0 epoch (that means when you use reference transformation to PZ-90.11 you will get January 2010 ...
