If you scaled objects physically by cost relative to a reference object, you could make some interesting graphics. For eg if the object is an iPhone ($1000, 6”), a $20,000 sedan would be about 12’ which is about right. So average value/unit volume is about the same.

An apple would be nearly microscopic on an iPhone dollar scale. If it’s 50c/apple it would be about 75 microns. About the width of a human hair.

You could distort individual object parts this way based on cost contribution. For a car the engine and compute would be very big.

I bet cost scales roughly as square of average dimension. Most cost in engineered things is in the design of 2d complexity. Material cost is a function of volume but many things are hollow. Small things densely packed with electronics might be ^2.5.

Find that a lot of industrial equipment fits a similar model. Complexity, optics, computing, high-speed motion components… irrelevant. Just kilos.

Otoh… a mining tire can be $100,000… a car tire $150 say. It’s not 1000x smaller, more like 10x. So volume effects distort low volume industrial things
