This is a converter for units of area. Non-decimal units are partitioned into the
correspondig subunits.

The values of the **Imperial** system in the United Kingdom and in the
**U.S. customary** system are the same (e.g. international inch).
In the U.S.A. the **U.S. survey**-system is still in use for land survey.
These areas are a little larger.

**Usage:**
Type the known values into the fields in front of the corresponding units.
After a mouseclick on any free space of the window or on the "calculate"
button the calculation is performed. Read the result.

In the non-metric unit systems you may choose the units for display
by a click on the corresponding checkbox. Units not chosen have a darker background.
The calculated area is the sum of all displayed values in a system. The smallest
unit in each system is displayed with decimal partitioning, if needed. The values in the SI-units (km^{2}, ha, a, m^{2}, cm^{2})
each correspond to the total calculated area.

Move the mouse over a unit or click on it to read its full name.
For another calculation just change the input values or you may click the
"reset" button, eventually. A previous choice of units is not reset
by this.

**Example:** You want to convert 3 hectare into acre and square yard in the
U.S. survey system.
In the area for the U.S. survey units choose a. and yd^{2} to be displayed.
Type "3" into the field in front of "ha".
After a mouseclick on any free space of the window or on the "calculate"
button you can read the result. 3 ha corresponds to 7 acre and 1999.6 yd^{2}.
In U. S. customary units this would be 7 acre and 1999.7 yd^{2}.

**Remarks:**

- Please note the remarks about the
representation of numbers..

- There is no warranty for the calculation. Cactus2000 is not
responsible for damage of any kind caused by wrong results.

- Please send an email if you have suggestions or if you would like to see more
