Why do people who try to convince others to switch to metric focus so much on the conversions?

I think the best 'conversion' thing in metric is not the mm/cm/m/km type ones but the volumetric type ones: a cubic metre of water/ 1 tonne / 1000 litres
What's the equivalent un US units? 1 cubic yard / 1684.8 pound / 807.8961039 qt / 25852.675325 oz ?
slugs
Even then I don't find the weight particularly useful, because it only applies to liquids with the same density of water.
Also 1 gallon is 231 cubic inches. Idk why, but it is, and I've already looked into all of the weird imperial measurements previously xD
Most liquids are similar to water. I will fairly often see a liquid and can do a quick estimation of weight based on volume. 40L water canister? That's about 40kg. It takes no effort to calculate.
Fair point, it is usually things like syrup that end up having a massively different weight
Water is the most abundant liquid on our planet. And most liquids we interact with have a density very similar to water.
What's your argument? "Oh. The ratio of volume and mass units don't work for all the densities? Then it's useless.". What benefit would any other ratio that is worth to give up the 1L=1Kg water ratio?
ok, so i have a liquid (honey) with density of about 1.4 g/ml that is 1.4 tonne for the m^3
You had the same density of ~11.5lb/gal what is the above calculation?
just look at all that maths https://measuringstuff.com/how-much-does-a-gallon-of-honey-weigh/
[edit, shit my spelling is bad this morning]
231=3 * 7 * 11, just in case you wanted to buy enough to give each of your three children 11 cubic inches of orange juice every day for a week.
Ahh, yes, the classic two and a half eggs of daily OJ
Yum.
