A foot is 0,30m and a sq ft is 0,09m. I know some will say because 0,3 times 0,3 is 0,09 but that wouldn’t explain the break of logic as I perceive it.

Picture the sizes as literal squares. Start with a square one meter on each side—that’s one square meter. Divide it into thirds both horizontally *and* vertically, so you have three columns and three rows. Each row or column has three squares that are a foot on each side—ergo, nine square feet inside one square meter.
You’re dividing by three twice, once for length and once for height, hence the 1/9th instead of 1/3rd.

Yes a square meter is technically 10.7639 square feet, not nine, but that’s beside the point being made here.
