Marcy, One hectare is 10 000 m2. So an acre is about 0.4 Hectares. Or 2.5 acres to a Hectare.

Marcy
is an acre 40% of 1000 sq.meter??

Not used in Oz or NZ anymore but we still talk in acres! "how many acres do you have here?"
We use centimetres/metres too but talk about our height "my eldest son is 6'6" six foot six inches" (which is true!).
