Fractions are easier to do calculations in your head or on paper than trying to do the same stuff in decimals. E.g. half of 1/2 is 1/4, half of 1/4 is 1/8, half of 1/8 is 1/16, half of 1/16 is 1/32 etc. In decimals this would be 0.5 -> 0.25 -> 0.125 -> 0.0625 -> 0.03125. When building stuff, I find it useful to be able to do that kind of stuff in my head easily.
Even though fractions makes sense for accuracy in a mathematical point of view, I see no benefit in a practical application.

Tell me you’re American without telling me you’re American.
why use decimals when you can use the… you know, actual weight of the thing?
How is saying “this weighs .25 kg“ not using the “actual weight of the thing”?
I get what you mean, but its adding a useless complexity layer.
If the thing always is smaller than, for example, a kilogram, just use the next measurement unit, a gram. 100g, 200g, 500g, etc.
It’s true the other way around, if the thing is always bigger than, for example, a kilogram, use it as is. 1kg, 1.5kg, 4kg, 6.2kg.
For ease of comparison, always use the most significant unit.
