This is a converter for units of area. Nondecimal 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. surveysystem 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 nonmetric 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 SIunits (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:
 Large and small numbers are written exponentially. As example
2.3e5 = 2.3⋅10^{5} = 230000 or
4.5e5 = 4.5⋅10^{5} = 0.000045.
 There is no warranty for the conversion. Cactus2000 is not
responsible for damage of any kind caused by wrong results.

conversions to be included.
