Abolish the Hectare

A few decades ago Great Britain changed its system of measurement to conform to European standards. I approved of that change, but think it should have been accompanied by a change in European measurements to make them conform to the standards of scientific measurement.

There is a general rule that the ratio between named units for the same quantity should be powers of a thousand.

Thus units of distance are ...micrometeres, millimetres, metres, kilometres..,

The units of area should therefore be square metres, thousands of square metres, square kilometres. Instead of those units people still use ares (1 are = 100 square metres), and hectares (1 hectare = 100 ares = 10 000 square metres).

Abolish those absurd units at once !!!
