>but for everyday general measures they all suck
They work fine.
>Temperature
0 is cold, 10 is chilly, 20 is comfortable, 30 is hot, 40 is very hot.
>Carpentry
Works fine. No idea what you are talking about.
>weights for everyday items
Work excellently. Nothing wrong with 500g of this, 1kg of that and 80g of a third thing.
>Meter too long, centimeter too short
Are you afraid of numbers? Is anything greater than 10 hard for you to comprehend?
