The cost of goods has the same units as the cost of shipping: $/kg. Referencing between them lets you understand how the economy works, e.g. why construction material sourcing and drink bottling has to be local, but oil tankers exist.

• An iPhone costs $4,600/kg, about the same as SpaceX charges to launch it to orbit. [1]
• Beef, copper, and off-season strawberries are $11/kg, about the same as a 75kg person taking a three-hour, 250km Uber ride costing $3/km.
• Oranges and aluminum are $2-4/kg, about the same as flying them to Antarctica. [2]
• Rice and crude oil are ~$0.60/kg, about the same as $0.72 for shipping it 5000km across the US via truck. [3,4] Palm oil, soybean oil, and steel are around this price range, with wheat being cheaper. [3]
• Coal and iron ore are $0.10/kg, significantly more than the cost of shipping it around the entire world via smallish (Handysize) bulk carriers. Large bulk carriers are another 4x more efficient [6].
• Water is very cheap, with tap water $0.002/kg in NYC. But shipping via tanker is also very cheap, so you can ship it maybe 1000 km before equaling its cost.

It's really impressive that for the price of a winter strawberry, we can ship a strawberry-sized lump of coal around the world 100-400 times.

[1] iPhone is $4600/kg, large launches sell for $3500/kg, and rideshares for small satellites $6000/kg. Geostationary orbit is more expensive, so it's okay for GPS satellites to cost more than an iPhone per kg, but Starlink wants to be cheaper.
