I followed this chain of reasoning:

By calculation (generator: ["now@trueknowledge.com"]) I know that:
The current time is February 13th 2012, 13:38:04

By calculation (generator: ["second_parameter@trueknowledge.com"]) I know that:
acre is the second parameter of 780 acres

I know from locally stored knowledge that:
square foot is the optimum conversion unit for acre ([fact: ["644332664@trueknowledge.com"]])

Fact 1: 43,560 is the multiplier that converts acre and square foot ([fact: ["644332720@trueknowledge.com"]])

Fact 1 is true for all time ([fact: ["1050413370@trueknowledge.com"]])

By calculation (generator: ["tpintersect@trueknowledge.com"]) I know that:
all time is the timeperiod intersection of all time and all time

By calculation (generator: ["product@trueknowledge.com"]) I know that:
0.40468564223999 is the product of 43,560 and 0.00000929030399999976

By calculation (generator: ["multiplier_that_converts2@trueknowledge.com"]) I know that:
Fact 2: 0.40468564223999 is the multiplier that converts acre and hectare

Fact 2 is true for all time

By calculation (generator: ["timeperiodtopoint@trueknowledge.com"]) I know that:
Fact 2 is true at February 13th 2012, 13:38:04

By calculation (generator: ["multiplier_that_converts2@trueknowledge.com"]) I know that:
Fact 2 is true for the beginning of time onwards

By calculation (generator: ["tpintersect@trueknowledge.com"]) I know that:
the beginning of time onwards is the timeperiod intersection of all time and the beginning of time onwards

By calculation (generator: ["first_parameter@trueknowledge.com"]) I know that:
780 is the first parameter of 780 acres

By calculation (generator: ["product@trueknowledge.com"]) I know that:
315.654800947192 is the product of 0.40468564223999 and 780

By calculation (generator: ["class_parametered_object@trueknowledge.com"]) I know that:
area is the class of the parametered object 780 acres

By calculation (generator: ["parametered_object_corresponding_to@trueknowledge.com"]) I know that:
315.654800947192 hectares is the parametered object corresponding to area and 315.654800947192 and hectare

By calculation (generator: ["equivalent_to6@trueknowledge.com"]) I know that:
Fact 3: 315.654800947192 hectares is equivalent to 780 acres

Fact 3 is true at February 13th 2012, 13:38:04

Fact 3: hectare is the unit used in 315.654800947192 hectares

I used the following facts to provide this answer:

square foot is the optimum conversion unit for acre

agree disagree edit

43,560 has always been the multiplier that converts acre and square foot and will be forever

agree disagree edit
