> 1 acre = 43560 ft^2 (exactly, 정확한 값)

> 1 ac = 43560 ft^2

 

> 1 hectare = 10000 m^2 (exactly, 정확한 값)

> 1 ha = 10000 m^2

 

 

> 1 ft = 0.3048 m (exactly, 정확한 값)

 

(1 ha) (10000 m^2 / 1 ha) (1 ft^2 / 0.3048^2 m^2)

= (1) (10000) (1 / 0.3048^2)

= 107639.104167 ft^2

 

 

> 1 hectare = 107639.104167 ft^2

120 × 75 = 9000 ft^2

 

 

 

($6500 / 9000 ft^2) (43560 ft^2 / 1 ac)

= (6500 / 9000) (43560)

= $31460/ac

= $31000/ac

= $3.1×10^4/ac

 

 

 

 

($6500 / 9000 ft^2) (1 ft^2 / 0.3048^2 m^2) (10000 m^2 / 1 ha)

= (6500 / 9000) (1 / 0.3048^2) (10000)

= $77739/ha

= $78000/ha

= 7.8×10^4/ha

 

또는

($6500 / 9000 ft^2) (107639.104167 ft^2 / 1 ha)

= (6500 / 9000) (107639.104167)

= $77739/ha
