In industry, everything is water...

[RobWed]

I may have gone down a rabbit hole here, (which I can assure you has never happened before...), but, while testing industry assets, I found that every unit of a given good (okay, I didn't test EVERY one but I tested enough!) has a volume of 1 litre and a weight of 1 kilogram. The ratio of units to item to kilograms to litres is 1:1:1:1.

As a bit of a back story for those of you as yet unacquainted with the beautiful symmetry of the metric system, water is it's very foundation. The keystone in the arch! One litre of water weighs one kilogram and, at 20C, occupies a volume of 0.01 metres cubed. If you're working in Freedom Units the truth is a little more obscure; 1:1:0.908:0.264 (approximately).

The relevance of this should be obvious. In the words of General Jack D. Ripper: "Water is the source of all life. Seven tenths of this earth's surface is water. Why do you realize that 70% of you is water? And as human beings, you and I need fresh, pure water - to replenish our precious bodily fluids."

That simply means that the base measurement of all products when expressed as a volume will be in litres, when expressed as a weight will be in kilograms (or imperial equivalents).

It does not mean that for a given product every litre will weight a kilogram - two exceptions being water and (strangely) duck down. It just means that you can have the load expressed as a volume (litres/gallons) or as a weight (kilograms/tons). I am certain that the script in each industry assets does not have a mass density conversion table that would correctly convert between weight and volume for every product.

A litre of lead, for example, would weight about 11.3 kg but a litre of duck down would weight almost exactly 1 kg.

Well I couldn't find lead or duck down as a product...

But I had a look at some of the config files for products and there IS a mass tag. I tested some other industry kind assets and it seems that a unit has a volume of a litre. So the density can be calculated. It would appear that the particular industry asset I was testing is not making use of this tag. Hence its universal 1:1:1:1 ratio

There are 4 basic types of products
- liquid loads and bulk loads -- these are measured in liters, the mass tag defining the density (kg/l)
- container loads and passengers -- these are measured in units, the mass tag defining the mass of 1 unit (kg)
