  • It is a real problem if everyone switched at once, which isn’t realistic. Even with a gradual approach, at some point residential areas will require upgraded supply lines if every house has 1 or 2 240v chargers. The upgrade cost will probably start becoming an issue in roughly a decade, unless something drastic changes with power supply.

    The fraction allows you to communicate length and tolerance in a single number. A decimal implies precision to the last number, a measure with a fraction can show 1/8 as more granular than 1/16. 1/8 of a cm is less precise than a mm, but if you wrote 1.125 cm, you are now implying sub mm level precision.

    This matters because the level needed in building generally doesn’t line up to 1/10 measurements. For example if you had a brick wall and a row had 1 cm height differences between bricks in a row it would be extremely obvious and look terrible. A 1mm height difference would be impossible to notice, but is also overkill to get that level. Ideal is about 5/8 cm or 6.35 mm difference over 3 meters of wall. The fractional measure often ends up easier to work with in practice.
