Limits and basis with

The kanji 以 has two meanings: one indicating “using” a means or basis, and the other indicating “from” a starting point in time or place.

Bounds

(Above)

以上(いじょう) means “at least” or “and above” when setting an inclusive lower limit. It can also mean “the preceding”, mark the end of a report, or introduce a conclusion based on what came before.

It combines 以 (basis) with 上 (above) to show what lies at or above the set point.
